Dissertação Acesso aberto (Open Access) Aplicação de tentativas discretas por cuidadores para o ensino de habilidades verbais a crianças diagnosticadas com autismo(Universidade Federal do Pará, 2015-08-25) SILVA, Álvaro Júnior Melo e; BARROS, Romariz da Silva; http://lattes.cnpq.br/7231331062174024The cases of Autism Spectrum Disorder (ASD) are characterized by persistent deficits in communication and social interaction in multiple contexts. The diagnosis of ASD also involves the presence of repetitive behavior and restricted interests. Considering the need of intervention and the lack of qualified professionals to implement intervention the purpose of this study was to verify the effects of parent-implemented teaching programs (VI) on the performance of children (VD). Participants included three children diagnosed with autism and their respective caregivers. Through a multiple probe design, the independent variable (IV) was selectively implemented on each of the teaching programs. Caregivers carried out the intervention at home and had their performance, and the performance of their children, was evaluated in sessions conducted in the room of the APRENDE Project/UFPA. Their performance was monitored during every session. Two or more programs were selected for each child. Participant 1 reached criterion for performance accuracy in the following programs: "Tact of Actions", "Mand with Autoclitic", and "Intraverbal of Personal Informations" after 7, 13, 19 sessions, respectively. Participant 2 needed 24 to 48 sessions and the Participant 3, 5 to 38 sessions to achieve accuracy in the programs. Data show that the intervention via caregiver, guided by a behavior analyst, can be effective and appropriate to the social-economic context of Brazil, characterized by lack of governm.Dissertação Acesso aberto (Open Access) Aquisição de relações condicionais simétricas e não simétricas e formação de classes por Cebus apella(Universidade Federal do Pará, 2010) SOARES FILHO, Paulo Sérgio Dillon; BARROS, Romariz da Silva; http://lattes.cnpq.br/7231331062174024Difficulty in documenting class formation in non-human participants may be due to the use of standard training and testing procedures developed in the context of research with human participants. Differences among testing and training situation may produce a decrease in performance during test. Using capuchin monkeys (Cebus spp.) as subject, this study intended to compare acquisition curve of a symmetrical with non-symmetrical conditional relation tasks, with different baselines for each conditional relation trained. This comparative analysis may provide us with some evidence of class formation without the need of the stimulus equivalence standard test protocols. Two male capuchin monkeys (Cebus spp.) participated: a young-adult (M09) and an adult (M12), both with history of simple and conditional discrimination training. Six pairs of bi-dimensional stimuli were used (A1-B1, A2-B2, A3-B3, A4-B4, A5-B5, and A6-B6). The procedure comprised three phases. In Phase 1, a “preparatory” 0-delay arbitrary matching to sample training was carried out (A1-B1 and A2-B2). In Phase 2, a "consistent" or “symmetrical” arbitrary matching to sample training was carried out (A3-B3, A4-B4, B3-A3, and B4-A4). In Phase 3, a "inconsistent" or “non-symmetrical” arbitrary matching to sample training was carried out (A5-B5, A6-B6, B5-A6, and B6-A5). Subject M12 finished all phases of the experiment. The comparative analysis between symmetrical and non-symmetrical acquisition curves (subject M12) shows easier acquisition of symmetrical task than non-symmetrical relations, suggesting that the arbitrary related events are members of class. This data suggest that the comparison between acquisition curves, such as it is described here, is a promising way to evaluate class formation in non-human participants. Subject M09 was removed from experiment because his performance did not reach the criterion in phase 3.1. M09 results pointed the need of a refined control relations analysis during the MTS task, making possible to improve the training procedure.Dissertação Acesso aberto (Open Access) Avaliação de simetria por comparação de treinos de emparelhamento ao modelo sucessivo (go/no-go)(Universidade Federal do Pará, 2013-09-16) PICANÇO, Carlos Rafael Fernandes; BARROS, Romariz da Silva; http://lattes.cnpq.br/7231331062174024Successive matching-to-sample (go/no-go) has been pointed out as an effective procedure to reduce stimulus control digressions in conditional relation training with non-humans. Other studies suggest the comparison between (symmetrical and non symetrical) conditional discrimination acquisition curves as a way to evaluate properties of equivalence relations. This study aimed to evaluate the potential of using both procedures above mentioned in evaluating the property of symmetry in four capuchin monkeys (Sapajus spp). Stimulus presentation, activation of devices, and response recording were automatically controlled by software. Subjects were maintained under conditions approved by IBAMA. By mean of an “ABAB” single subject design, the acquisition of symmetrical (A) and non-symmetrical (B) conditional discriminations were compared. In both Condition A and B, conditional relations A-B and B-A were simultaneously trained so that in every condition, four new arbitrary conditional discriminations (with new stimuli arbitrarily related) were presented. When symmetrical, positive combinations were A1-B1, A2 B2, B1-A1, and B2-A2, and negative combinations were A1 B2, A2 B1, B1 A2 and B2 A1. When non-symmetrical, positive combinations were A1 B1, A2 B2, B1 A2, and B2 A1, and negative combinations were A1 B2, A2 B1, B1 A1 e B2 A2. Two of the four subjects (Negão e Bongo) completed que acquisition of one (Bongo) or two (Negão) sets of conditional relations (Conditions A-symmetrical and B-non-symmetrical) for the evaluation of the viability of the procedure to verify the property of symmetry. Data demonstrate that the method here reported detected the presence of the property of symmetry in the conditional relations leraned by Negão and its absence in the conditional relations learned by Bongo. Data are inconclusive for the other two subjects. One detailed analysis of the performance of each subject and its measures is also presented.Dissertação Acesso aberto (Open Access) Avaliando a alteração da função de faces via equivalência de estímulos e pareamento de estímulos tipo respondente (ReT) em crianças com TEA(Universidade Federal do Pará, 2020-04-28) BORDA, Gisell Andrea Díaz; SILVA, Álvaro Júnior Melo; http://lattes.cnpq.br/8960291779730857; BARROS, Romariz da Silva; http://lattes.cnpq.br/7231331062174024; https://orcid.org/0000-0002-1306-384XChildren with atypical development may have deficient face observation behavior. This deficit may explain, in part, some of their difficulties in social interaction and acquisition of complex behavior such as the verbal repertoire. The present dissertation explored the effect of two types of procedures: equivalence-based instruction and stimulus pairing, on the alteration of face functions measured by preference tests for human faces figures and duration of human face observation responses in social tests. The behavioral processes involved in face observation responses in children diagnosed with Autism Spectrum Disorder (ASD) were researched in the two studies presented here. Experiment I, evaluated the effect of equivalence-based instruction on the potential transfer of function from preference figures items to figures of human faces and properly human faces. Three children diagnosed with ASD participated in the study. A Pre-test and post-test design was used, with multiple baseline temporal controls, divided into three phases: a) Pre-test: assessment of the choice responses and face observation, b) Intervention: equivalence class formation via identity matching with class-specific consequences, c) Post-test: repetition of measurements made in Pre-test phase. Results demonstrated that, despite the difficulty in documenting the emergence of conditional relations that prove properties of equivalence relations (only symmetry was obtained for two of the three participants), changes in choice responses to figures of human faces was evidenced in two participants. One of the participants showed also changes in social tests. However, in the reinforcement phase of the conditional relations of this study, there was pairing between stimuli: access to a high magnitude preference item is preceded by the presentation of a visual stimulus (figures of human faces). Therefore, Study II assessed the possible effect of this pairing alone on the function of faces in children diagnosed with ASD. Two children who did not participate in Study I took part in Study II. An intra-subject design comparing Pre-test and Post-test measures was implemented, organized in a multiple probe schedule between participants, divided into three phases: a) Pre-test; b) Intervention: respondent-type (ReT) pairing between pictures of faces and highly preferred item and between an abstract figure and a lower preferred item, and c) Post-test: repetition of Pre-test measures as described in Study I. Study II, therefore, was complementary to Study I. The results in Study II show alteration of responding to faces in preference tests and social tests for one of the two participants. The data obtained in this dissertation add basic research knowledge to identify behavioral processes involved in the human facial observational responses, as well as provide relevant information to the area of Applied Behavior Analysis to the intervention of children who have difficulties in attention to faces. The procedures explored point to the use of methodological strategies to alter the function of the faces and show the potential of the stimulus equivalence paradigm in altering observation responses.Dissertação Acesso aberto (Open Access) Cognição animal: identidade generalizada e simetria em macaco-prego (Cebus apella)(Universidade Federal do Pará, 2003-02-14) SANTOS, José Ricardo dos; BARROS, Romariz da Silva; http://lattes.cnpq.br/7231331062174024Complex behavioral repertories, such as generalized identity matching and equivalence classes, have been easily found in normal humans, children, and youngsters with learning deficits. However, it is not easy to find such a positive results with non-human subjects. Symmetry is one of the most difficultly found defining properties of equivalence in nonhumans. It might happen because symmetry involves sample-comparison function reversals as well as modification in the sequence and position of stimuli presentation. The negative results in obtaining generalized identity matching and equivalence class formation in non-humans subjects may be related to incoherence between the SCT (Stimulus Control Topography) planned by the experimenter and the SCT presented by the subjects. So it suggests the necessity of a more specific methodological development. The present study proposed to apply the training and testing experimental procedures to obtain generalized identity matching and to verify the possibility of emergence of symmetry after arbitrary matching to sample training, through sample stimulus control shaping procedure and in the absence of correlation between the function and the positions of the stimuli. One capuchin monkey (Cebus apella) served as subject. He was young-adult and naive. Two experiments were executed. In the Experiment I, we carried out simple discrimination reversals training, conditional discrimination training, with an identity matching to sample procedure, and generalized identity test in extinction. The results showed that the procedure used to train simple discrimination (and reversals) was efficient as well as the procedure to train identity matching. All generalized identity tests reached positive results. In the Experiment II, we carried out arbitrary matching to sample training, with a sample stimulus shaping procedure in 8 steps, and one BA symmetry test. This study aimed to verify if elements positively related in conditional discriminations (AB training, for example) might be recombined by the subject without additional training. The performance of the subject in the BA symmetry test reached 100% of correct choices, showing that it is possible to obtain the property of symmetry in arbitrary conditional discriminations with non-humans subjects. The data also suggest that additional research has to be carried out in order to contribute to specifying the necessary conditions to obtaining complex repertory such as equivalence class formation in non-human subjects.Dissertação Acesso aberto (Open Access) O efeito de vídeos de alimentação saudável sobre as escolhas de alimentos em crianças(Universidade Federal do Pará, 2014-04-10) SOUZA, Gilvandro Figueiredo; KATO, Olívia Misae; http://lattes.cnpq.br/3612219210222465; BARROS, Romariz da Silva; http://lattes.cnpq.br/7231331062174024Videos about of nutrition education, publicity, advertising and entertainment are widely used as a means of communication. Many of them are used to encourage the consumption of foods. However, most of the time, the videos that talk about such consumption, focus on the development of broad dissemination of high in fat, sodium and sugar foods, in excess, are harmful to health. All this disclosure just promoting an increase in the consumption of unhealthy foods and, consequently, reducing the practices of good nutrition education. Based on this fact the Study 1 was conducted to evaluate the effect of videos about healthy food choices healthy food for children. What was to present, through educational videos, the various types of foods consumed by man. As participants in this study among children aged between 10 and 11 years old that might among the various types of food make your own choice. Participated in Study I, 24 children between 10 and 11 years of age, of both sexes, regularly enrolled in elementary school. The study I was divided into three stages. In the Stage I the appointment of foods was assessed with appropriate phase correction. In the Stage II, children were exposed to pre - test selection of healthy and unhealthy foods, the videos of healthy foods, the assessment of understanding of test videos, and finally again to test food choices. In the Stage III consisted only in the testing of food after a week of intervention. The results indicate that the videos showed effect on most healthy choices for children. But, this effect was temporary. In Study II, a questionnaire was applied to verify the food preferences of children in the same study 1 and 164 other children of the same grade and age. The results indicate that there is a slight preference for unhealthy foods, but in general, preference is given at a ratio of 1/1. Studies investigating the control variables of feeding behavior are extremely important for preventing obesity, promoting healthy habits and discussion of public policy Nutritionally, Industrial, Commercial and Consumer Behavior.Dissertação Acesso aberto (Open Access) Efeitos da manipulação do número de escolhas sobre o desempenho em tarefas de discriminação simples em macaco-prego (Cebus cf. apella)(Universidade Federal do Pará, 2010-11) QUEIROZ, Lidianne Lins de; BRINO, Ana Leda de Faria; http://lattes.cnpq.br/9930065472602966; BARROS, Romariz da Silva; http://lattes.cnpq.br/7231331062174024There are several variables that can affect the precision of repertoire acquisition in discrimination training. The number of choices presented in the discrete trials is still one variable little explored in the context of verifying in which situations the discriminative control is more easily established. The general objective of the present work is to describe the effects of the manipulation of the number of choices on performance in simple discrimination tasks in capuchin monkeys (Cebus cf. apella). In Experiment I, the subjects were given a discriminative training with three types of trials (2, 4, and 9 choices). A stimulus control test assessed if the acquired repertoire could be maintained when the stimuli used in the three types of trials were then presented in the two-choice fashion. Additionally, in Experiment II, we evaluated if the correct responses in previous discrimination training occurred due to selection of the S+, rejection of the S-, or mixed control (selection and rejection). This evaluation was carried out through a mask procedure. The results in Experiment I suggest that the exposure to a larger number of choices is an efficient strategy to establish the discriminated responses since the performance was accurate even when the number of choices was reduced to two. The results obtained in Experiment II show different data for the two subjects. M30 showed control by rejection and preference for mask and M31 showed mixed control. The present research shows a path to a more complete analysis of stimulus control in studies on the manipulation of the number of choices and indicates that this variable may be an efficient way to reduce the difficulty in acquisition of discriminations in applied context.Dissertação Acesso aberto (Open Access) Efeitos de pareamento estímulo-estímulo sobre respostas a vozes e faces em crianças diagnosticas com autismo(Universidade Federal do Pará, 2015-03-06) MOREIRA, Jenifer Léda Muniz; BARROS, Romariz da Silva; http://lattes.cnpq.br/7231331062174024Children diagnosed with Autism Spectrum Disorder (ASD) may have, among other deficits, low frequency of visual contact (look at the face of another person) and little interest in human voices. This can affect the social development and acquisition of verbal repertoire. This study aimed to evaluate the effect of stimulus-stimulus pairing procedure on: (1) the preference for human faces and voices of two children diagnosed with autism and (2) the performance of such participants in a set of social tests. The procedure was divided into two phases: 1) face conditioning and 2) voice conditioning. Phase 1 comprised baseline evaluation (multiple measures of responding to face figures and face itself) and face conditioning (“face-figure/reinforcer” pairing and “face/reinforcer” pairing). Phase 2 consisted of assessment of preference for voices, followed by voice conditioning, in which the reproduction of recorded voices was paired with the reinforcers. Frequency and duration of attend to voices and faces were measured in pre and post tests. The results show that measures based on response time were more appropriate to assess the effects of manipulation, with more evident effect of “voice-reinforcer” pairing than visual pairing. This study describes advances with respect to operant repertoires (observing responses) that result in exposure to human faces and voices in children diagnosed with autism. It is suggested that future studies explore possible functional relation between voice and face conditioning on the acquisition of other repertoires such as joint attention response, joint attention initiation, as well as verbal repertoires, such as tact and mand.Dissertação Acesso aberto (Open Access) Efeitos de videomodelação instrucional sobre o desempenho de cuidadores na aplicação de programas de ensino a crianças diagnosticadas com autismo(Universidade Federal do Pará, 2015-03-25) BARBOZA, Adriano Alves; BARROS, Romariz da Silva; http://lattes.cnpq.br/7231331062174024Caregiver teaching has been a promising methodology to face the arising demand of individuals diagnosed with developmental delays, especially those with Autism Spectrum Disorders (ASD). This study aimed to develop and evaluate the effect of a package of instructional videomodeling on the performance accuracy of caregivers in implementing teaching programs to children diagnosed with ASD. The videos used had, as essential elements: exhibition of multiple exemplars, subtitles, narrations, and visual cues throughout the video. A multiple-baseline design across participants was used to measure the effect of the videomodeling procedure on the performance accuracy of the caregivers. Three parents of children diagnosed with TEA participated: Alice, Cassio, and Fernanda, who presented, respectively, 6%, 25%, and 45% average accuracy throughout baseline measures. After videomodeling procedure, performance accuracy reached 83%, 88%, and 80% average accuracy. Considering such results, we believe that the procedure of instructional videomodeling is promising to disseminate behavioranalytic intervention, in a less resource demanding way. Subsequent research should improve the intervention package here described, in order to obtain better results and provide a tool to disseminate behavior analytic intervention to wider portions of the affected population.Dissertação Acesso aberto (Open Access) Ensino de relações arbritárias e busca de simetria em Cebus apella(Universidade Federal do Pará, 2010-02) FONSECA, Abraão Roberto; BARROS, Romariz da Silva; http://lattes.cnpq.br/7231331062174024For some theorists, the lack of control over procedural variables has made difficult documenting equivalence classes in nonhuman subjects or human participants with developmental disabilities. The present research was divided in two experiments. The Experiment I aimed to evaluate the combined use of procedures such as “specific reinforcement”, “variations of S-“, “blocks of trials gradually smaller”, and “omission of previous S+ on the next trial block” in arbitrary relations training and symmetry test. A young male capuchin monkey (Cebus apella), Guga, served. The procedure comprised the following phases: pre-training, simple discrimination training, arbitrary relation training (A1B1 and A2B2), and symmetry test. The results show that Guga finished the arbitrary training in 39 sessions. The results of symmetry test show accurate performance for one relation and chance level accuracy for the other, with accurate performance in the first test trial for both relations. In Experiment II, two new relations (A3B3, A4B4) were added to the baseline (A1B1, A2B2). The results of the symmetry test for the new relations show accurate performance concerning to one relation and 75% of accuracy for the other. The present study encourages the development of procedures to reduce stimulus control incoherence and reinforces the possibility that the difficulty to document equivalence class formation in nonhumans relays on procedural variables.Dissertação Acesso aberto (Open Access) Formação de classes de equivalência através de reforçamento específico em crianças com dificuldades de aprendizagem(Universidade Federal do Pará, 2007-08-01) PORTO, Allana Ribeiro; BARROS, Romariz da Silva; http://lattes.cnpq.br/7231331062174024In Behavior Analysis, several studies have been carried out in order to understand how behavior can be productively controlled by arbitrarily related events, through equivalence class formation. The inclusion of reinforcer stimuli in the classes has been pointed as a possible facilitator of their formation. The present study aimed to evaluate the formation of equivalence classes mediated by reinforcer stimuli with children with mild learning difficulties. By using normally developing children and in a larger number we intended to obtain data with less across subject variability, which is commonly found in this kind of research. It was used specific reinforcement with fourteen children that showed mild learning difficulties at school (Experiment 1). The experiment comprised 10 phases. In all phases, there were specific reinforcers (fruit or toys) to each of the potential classes. Initially we carried out an identity matching-to-sample procedure with the stimuli of the sets A (A1 and A2), B (B1 and B2) and C (C1 and C2) in a continuous reinforcement schedule, followed by an intermittent reinforcement schedule. Then, tests for emergent relations ABBA, ACCA, and BCCB were carried out. Before each test, we returned to the baseline training. Data from Experiment 1 show great across subject variability. The Experiment 2 was to investigate the effect of two different kinds of pre-training on the performance in tests for class formation. Six children participated and they were divided into two groups. Group 1 was trained with identity matching-to-sample and Group 2 with arbitrary matching-to-sample. The results confirm partly the hypothesis that arbitrary MTS as pre-training may reduce across subject variability in this kind of research, because high rates of variability were found in this study. Further research will explore this possibility more systematically.Dissertação Acesso aberto (Open Access) Formação de classes de equivalência via consequências específicas em crianças com autismo(Universidade Federal do Pará, 2014-02-25) SANTOS, Eugênia Andréa Leão; BARROS, Romariz da Silva; http://lattes.cnpq.br/7231331062174024Some previous studies, reporting equivalence or functional class formation with classspecific consequence procedures, found inter-subject variability due to loss of reinforcers efficacy. In the present study, we evaluated (1) the efficacy of introducing variations of events (within a category) as class-specific consequences and (2) the inclusion of such consequences into the equivalence classes. Two children diagnosed with autism participated. They were given identity matching to sample training (stimulus set A) and simple discrimination reversal training (stimulus set B). A variety of videos of a same theme plus a variety of food within the same category (such as sweet or salty) were used as class-specific consequences. Probe trials tested for the emergent arbitrary relations AB and Consequence-A relations. Both participants showed 100 percent of accuracy in baseline discriminations after four 24-trial training sessions. The accuracy criterion for performance in test blocks, to consider that the tested relations emerged, was (a) choose the stimulus S+ in the first test trial of each tested relation and (b) choose the S+ on at least five out of six trial in the test block. Performance of both participants reached the criterion and showed the inclusion of the classspecific consequences in the classes. The data reported here (1) show that the use of classspecific consequences comprising a variety of elements was efficient to maintain reinforcement efficacy; (2) confirm theoretical predictions on the inclusion of reinforcers into the equivalence classes, and on the possibility of equivalence relations in three-term contingencies; (3) encourage the use of similar procedures in applied context.Dissertação Acesso aberto (Open Access) Intervenção implementada por profissional e cuidador a crianças com TEA(Universidade Federal do Pará, 2017-08-28) OLIVEIRA, Juliana Sequeira Cesar de; BARROS, Romariz da Silva; http://lattes.cnpq.br/7231331062174024Applied Behavior Analysis (ABA) has been shown to be effective in intervention for people with autism. In Brazil, analytical-behavioral services are not accessible to a large portion of the population, which does not have the financial means to afford high intervention costs. More accessible intervention can be through by caregivers teaching. There is a considerable amount of studies in the international and national literature showing that parents may be able to apply teaching accuracy to children with autism. In this sense, a question arises: how comparable is the result of intervention implemented by caregivers and professionals? Thus, the objective of the present study was to compare the application of the caregiver application in relation to the application by professionals in training with children with autism. Three children with autism, their caregivers and five professionals participated in the study. The sessions happened at UFPA and at the children's home. The experimental design used was the use of multiple probes between teaching programs with alternation between treatments (implementation by caregivers and by professionals). The dependent variable was the percentage of accuracy of performance of the child in each teaching program. The results show no critical difference between caregiver and professional implementation. An average number of attempts for Lucila to archive criterion in the teaching programs was 78 trials (professional) and 58 trials (caregiver), with a standard deviation of 11.3 and 18.7 respectively. An average number of trials for which Lucas to archive the criteria of 49.9 trials (professional) and 58.8 (caregiver), with the standard of 19.9 for both interventions. For Daniel, the intervention was interrupted to start a specific training of inappropriate behavior management for the caregivers. The results of this study are the beginning of a major research line on ABA concerning to autism and it suggests that caregiver implementation can be as efficient as the professional implementation.Dissertação Acesso aberto (Open Access) Procedimentos para determinação e identificação de relações de controle em tarefas de IDMTS em Cebus apella(Universidade Federal do Pará, 2008) BEZERRA, Débora da Silva; BARROS, Romariz da Silva; http://lattes.cnpq.br/7231331062174024Obtaining Type S and Type R control relations in Identity MTS (IDMTS) tasks may make possible the development of an accurate observing repertoire towards all the stimuli (S+ and S-). In this work, a sequence of procedures was used to generate or identify possible stimulus control relations present in IDMTS training and tests. The purposes of the present work were: a) verify the viability of the use of the mask procedure (blank comparison procedure) to identify or determine stimulus control relations in IDMTS tasks with capuchin monkeys, and b) evaluate the efficacy of this procedure to test for stimulus control relations. Two male capuchin monkeys (Cebus apella) with previous experimental history participated. An experimental chamber equipped with a PC and touch screen monitor was used for stimulus presentation and response recording. In Experiment I, the subjects were given two-choice IDMTS training, mask procedure training, and biasing procedure training with the purpose of generating Type S and/or Type R stimulus control relations. Then, tests for stimulus control relations with mask procedure and new stimulus procedure were carried out. In Experiment II, we trained four-choice IDMTS tasks and tested for stimulus control relations via mask procedure. The results from Experiments I and II suggest that mask procedure was not effective to produce Type S and Type R stimulus control simultaneously, as well as the biasing procedure was partly effective to generate the expected Type S stimulus control. Forthcoming research, including better preparation for the blank comparisons effectively function as masks, has to be carried out. Research on this topic may bring up procedural variables that occasionally may be implied in the difficulty to obtain, for example, equivalence class formation in non-human subjects.Dissertação Acesso aberto (Open Access) Utilização de um guia instrucional para descrição de competências como uma ferramenta complementar no mapeamento de competências em órgãos públicos(Universidade Federal do Pará, 2017-08-21) BARTH, César Augusto; RAMOS, Camila Carvalho; http://lattes.cnpq.br/4681656913940932; BARROS, Romariz da Silva; http://lattes.cnpq.br/7231331062174024The competence management model was established in the Brazilian public administration through Decree nº 5.707/2006. This management model has been successful in defining the behavioral units necessary for the employees to carry out their work. The competencies required to carry out the work are the central axis of this management model, so it is essential that the competencies are well described. For greater reliability of the competence description , it is delegated to employees the responsibility for their description, thus, employee engagement is essential to obtain competence descriptions properly. For that end, we used a instructional guide for competence description. The objective of this study was 1) identify and manipulate the factors that potentially have impact on employee collaboration in competences description using an instructional guide and 2) evaluate the quality of the competences described with the use of the guide. A total of 349 employees participated. They were members of 15 competency mapping workshops in three Brazilian federal public agencies. The instructional guide was sent to the participants by e-mail, with instructions and a request for formulation of competencies until the date of the workshop. On the day of the workshops, employees were given a questionnaire with questions regarding the factors that helped or hindered them in describing the competencies. The responses of participants who performed and those who did not perform the task were compared and one identified factor was manipulated. Finally, the quality of competencies described in three conditions was compared: a) competencies described only with the use of the guide; b) competencies developed by the participants using the guide together as workshops and; c) competencies elaborated based only on the workshop. The results did not indicate significant differences between the competencies described by the employees who only participated in the workshops and those who participated in the workshops and used the instructional guide. The competencies described only based on the instructional guide sowed the greatest number of problematic conditions.
