- Características psicométricas e estrutura fatorial da FACES III numa amostra de famílias em risco psicossocialPublication . Nunes, Cristina; Ayala-Nunes, Lara; Ferreira, Laura Inês; Martins, CátiaEste estudo visou a adaptação e exploração das características psicométricas da Escala de Avaliação da Coesão e Adaptabilidade Familiar (FACES III) com uma população de famílias portuguesas em risco psicossocial. Esta medida é a mais utilizada para a avaliação do funcionamento familiar de acordo com as dimensões do Modelo Circumplexo dos Sistemas Familiares. Participaram 388 pais de crianças com medidas de apoio e proteção, residentes no Algarve. A FACES III foi aplicada em conjunto com medidas de stresse parental, aliança parental e sentimento de competência parental para testar a validade de constructo. A análise fatorial exploratória confirmou a solução original de dois fatores. A Coesão demonstrou alta consciência interna e boa validade de constructo, podendo ser considerada uma medida fiável desta dimensão. A Adaptabilidade apresentou resultados insatisfatórios em todos os indicadores psicométricos, pelo que se aconselha a revisão desta subescala. Os resultados são discutidos considerando as diversas versões do instrumento.
- Parenting Alliance Inventory: psychometric properties and invariance among a community and at-risk sample of Portuguese parentsPublication . Nunes, Cristina; Ayala-Nunes, Lara; Martins, Cátia; Pechorro, Pedro; Ferreira, Laura InêsThe existing alliance between the two caregivers is a key dimension for understanding the family context, as it affects parental behavior and children's development. The assessment of this construct becomes even more pressing in at-risk families, where the children's well-being may be compromised and where the parental alliance may serve as a protective factor. The Parental Alliance Inventory (PAI) is a self-report measure that assesses the parental alliance and the relationship of support and trust that exists between both parents. In this study, we intended to explore the psychometric properties of PAI in the Portuguese population, including normative and at-risk families. Participants were community parents (n = 205, M = 38.38 years; 52.2% women) and parents of Child Welfare Services (CWS) referred children (n = 273, M = 37.05 years, 82.05% women). Both samples completed the PAI and measures of parenting sense of competence, parenting stress, and marital satisfaction. Confirmatory factor analysis confirmed the proposed original unidimensional structure of the PAI. The instrument showed good psychometric properties, presenting levels of internal consistency and a quite satisfactory reliability. Findings also showed that PAI was measurement invariant across the two subsamples. Our findings provide evidence for psychometric soundness of the PAI and support its usefulness for the European Portuguese context.
- Parenting sense of competence: Psychometrics and invariance among a community and an At-Risk Samples of Portuguese ParentsPublication . Nunes, Cristina; Ayala-Nunes, Lara; Ferreira, Laura Inês; Pechorro, Pedro; Freitas, Délia; Martins, Cátia; Santos, RitaParenting sense of competence (PSC) is a cognitive and emotional construct that refers to the judgments that parents hold about their abilities as caregivers. It also includes parents’ beliefs about their capacity to positively influence their children’s development and their satisfaction with the parenting role [1–3]. This construct has been widely studied and is a relevant dimension for the assessment and understanding of family dynamics. Parenting sense of competence has been associated to several family dimensions, such as marital relationship and family functioning [2,4,5]. For instance, mothers’ sense of competence has been positively linked to coparenting support [6], and a reciprocal relationship between perceived parental competence and marital stress over a 6-year interval has been reported for both mothers and fathers [7]. It is especially important to assess this construct in families who are at psychosocial risk [8–12]—i.e., families that have difficulties in adequately meeting children’s needs but not severely enough to require children’s placement in foster care [13]. This is because research has suggested indirect relationships between PSC and potential for child abuse [14] and maltreatment [15]. Similarly, PSC is thought to be a protective factor for negative outcomes, buffering the impact of risk factors such as maternal depression, children’s difficult temperament, and disadvantaged environments [16,17].
- Psychometric properties of an adapted version of the parental sense of competence (PSOC) scale for Portuguese at-risk parentsPublication . Nunes, Cristina; Jimenez, Lucia; Menendez, Susana; Ayala-Nunes, Lara; Hidalgo, VictoriaParental sense of competence is one of the central dimensions targeted on psychosocial interventions aimed at supporting at-risk families. Researchers and practitioners need reliable instruments to assess the parental role adapted for these families. Although the parental sense of competence (PSOC) scale has been frequently used to assess this construct, there is still no adapted version for Portuguese parents. In this study, the reliability, validity and factor structure of the PSOC scale is examined with a clinical sample of 146 mothers from at-risk families receiving psychosocial interventions for family preservation from Child Protective Services. Results show that the Portuguese version of the PSOC measures three distinct constructs with acceptable psychometric properties: efficacy, dissatisfaction and controllability. As expected, the obtained factors were significantly and positively related to parenting alliance and family cohesion, and negatively associated with parenting stress. In sum, the proposed Portuguese version shows reliability and validity evidences to measure three relevant dimensions of parental self-evaluation, and it constitutes a cost- and time-effective instrument suited for at-risk mothers.
- Psychometric properties of the socially desirable response Set-5 among incarcerated male and female juvenile offendersPublication . Pechorro, Pedro; Ayala-Nunes, Lara; Oliveira, João Pedro; Nunes, Cristina; Gonçalves, Rui AbrunhosaThe main aim of the present study was to examine the psychometric properties of the Socially Desirable Response Set-5 (SDRS-5) among a forensic sample (N = 324) of incarcerated male (n = 221) and female (n = 103) juvenile offenders. The Portuguese validation of the SDRS-5 demonstrated good psychometric properties, namely in terms of its factor structure, internal consistency, convergent validity, and discriminant validity that overall justifies its use among this population. Findings are discussed in terms of the use of the SDRS-5 with male and female juvenile offenders. (C) 2016 Elsevier Ltd. All rights reserved.
- Quality of life of portuguese and spanish adolescents. A comparative study between natives and immigrantsPublication . Nunes, Cristina; Hernando Gomez, Angel; Lemos, Ida; Ayala-Nunes, Lara; Romero Oliva, Cristina; Montilla Coronado, CeciliaThe aim of this study was to analyse differences in quality of life (QOL) between Spanish and Portuguese immigrant and native adolescents. In total, 475 native and immigrant adolescents (52% boys) from Algarve (Portugal) and Huelva (Spain), aged between 12 and 17 years old, were assessed with the KIDSCREEN-52. QOL dimensions were not related to most academic variables, with the exception of number of school failures, Financial Resources and Social Support from Peers. Multivariate analysis of variance (MANOVA) was used to examine statistical differences in adolescents QOL. Age differences in QOL levels were not found. Girls reported worse QOL levels on Physical Wellbeing than boys (F = 10.32, p = .001, eta(2) = .02). Immigrant Portuguese adolescents scored higher on Mood (F = 17.57, p = .000, eta(2) = .11), and native Portuguese adolescents scored higher on Social Acceptance (F = 4.87, p = .002, eta(2) = .033). Immigrant and native adolescents had similar levels of perceived QOL. Overall, it seems that in both countries, the living contexts for immigrant and native adolescents are fairly homogeneous.
- Short Form of the Social Anxiety Scale for Adolescents among community and institutionalized Portuguese youthsPublication . Nunes, Cristina; Ayala-Nunes, Lara; Pechorro, Pedro; Greca, Annette M. LaBackground/Objective: Social anxiety is a common issue arising in adolescence that can cause significant impairment and have detrimental consequences for development in the absence of treatment. In this study we examined the factor structure and the psychometric properties of a 12-item short form of the Portuguese-Language Social Anxiety Scale for Adolescents (SAS-A-SF). Method: A community adolescent sample (N = 835) and a young offender sample (N = 244) completed the SAS-A, the Basic Empathy Scale and the Reactive-Proactive Aggression Questionnaire. Confirmatory factor analysis, internal consistency, cross gender and cross sample invariance, convergent and discriminant validity of the SAS-A-SF were analyzed. Results: The confirmatory factor analysis revealed that the 3-factor second-order model obtained the best fit. The results provided evidence that the SAS-A-SF is a psychometrically sound instrument that shows measurement invariance across genders and across samples, good reliability and positive correlations with empathy. Conclusions: The Portuguese version of SAS-A-SF is a useful, time-efficient tool for both researchers and practitioners who need to assess social anxiety, a relevant construct in adolescent psychopathology.

- The adapted DUKE-UNC functional social support questionnaire in a community sample of portuguese parentsPublication . Martins, Silvana; Martins, Cátia; Almeida, Ana; Ayala-Nunes, Lara; Gonçalves, Andrea; Nunes, CristinaPurpose: Social support measures have generated empirical evidence of helping relationships and their role in family functioning and well-being. Social support networks affect parental practices and the ways in which families overcome stressful life events. Thus, it is important to gather knowledge about the different forms of support that families can benefit from. The aim of this study was to translate, adapt, and validate the Portuguese version of the Duke-UNC Functional Social Support Questionnaire (FSSQ), a three dimension measure (confidant support, affective support, and instrumental support), Method: 1058 Portuguese parents participated in the study. They were mostly married/cohabiting and employed mothers. The Portuguese version of the FSSQ contained 13 items distributed into 3 subdimensions. The data were analyzed using confirmatory factor analysis and the study of Pearson correlations. Results: The FSSQ original three-factor structure was supported by confirmatory factor analysis and the instrument showed good internal consistency. Confidant support and Instrumental support were negatively associated with Permissive parenting and Affective support was negatively associated with Authoritative parenting and Permissive parenting. All three dimensions showed low and positive correlations with Authoritarian parenting. Discussion: The Portuguese version of the FSSQ met adequate psychometric criteria and can be confidently used in family assessments of social support, whenever a brief, self-administered questionnaire would be useful for community services providers
- The barratt impulsiveness scale-11 among a school sample of portuguese male and female adolescentsPublication . Pechorro, Pedro; Ayala-Nunes, Lara; Ray, James V.; Nunes, Cristina; Gonçalves, Rui AbrunhosaFew personality traits are as socially relevant as impulsivity, but few self-report measures have been specifically developed for adolescents and children. The aim of the present study was to examine the psychometric properties of the Barratt Impulsiveness Scale version 11 (BIS-11) among a mixed-gender sample of 782 Portuguese youth (M = 15.87 years; SD = 1.72), in a school context. Confirmatory factor analysis revealed the expected 6-factor first-order structure, but the 3-factor second-order factorial structure did not present a good fit. Cross-gender measurement invariance was demonstrated only in terms of weak invariance. Nonetheless, the Portuguese adaptation of the BIS-11 demonstrated some generally acceptable psychometric properties of internal consistency, mean inter-item correlation, convergent validity, discriminant validity, and criterion-related validity of statistically significant associations with conduct disorder symptoms, alcohol abuse, drug use, and unprotected sex. The use of the BIS-11 among the male and female youth population is psychometrically justified, and it can be a useful measure to identify impulsive adolescents who are at considerable risk of personal injury and present a potential source of injury to others.
- The ENRICH Marital Satisfaction (EMS) Scale: a psychometric study in a sample of Portuguese parentsPublication . Nunes, Cristina; Martins, Cátia; Leal, Andreia; Pechorro, Pedro; Ferreira, Laura Inês; Ayala-Nunes, LaraMarital satisfaction is a key construct in the assessment of a couple’s relationship, and it encompasses aspects such as the feelings of affection, trust, and companionship that arise from the exchanges between spouses. The ENRICH Marital Satisfaction (EMS) Scale has been widely used as a reliable measure to assess marital satisfaction. In the present study, we aimed to analyze the psychometric properties and the factor structure of the EMS Scale in a sample of Portuguese parents. A total of 205 mothers and fathers participated; 107 were women (52%), and 98 were men (48%), and the mean age was 38.39 years (SD = 5.85). The majority were two-parent families (89.3%), with children between the ages of 1 and 13 years (M = 6.90), 53% of whom were boys. The participants completed the EMS Scale together with the Parenting Stress Index Short Form and the Parenting Alliance Inventory. The results from a confirmatory factor analysis corroborate the two-dimensional structure of the instrument, with internal validity and reliability values that were suitable for application in the Portuguese population. The EMS Scale can be an important resource, with good psychometric quality, for professionals and researchers, which can be used in assessment and intervention programs, both at the individual and couple levels.
