- Portuguese Version of the Kansas Marital Satisfaction Scale: Preliminary Psychometric PropertiesPublication . Antunes, Natália; Vieira-Santos, Salomé; Roberto, Magda Sofia; Francisco, Rita; Pedro, Marta; Ribeiro, Maria TeresaMarital satisfaction is considered a core dimension to understand marriage quality, influencing individual and family well-being. The Kansas Marital Satisfaction Scale (KMSS) is one of the most used instruments to assess this dimension. This study presents the psychometric properties of the KMSS Portuguese version through two studies. In Study 1, 145 couples (parents of school-aged children) completed the KMSS, and the Co-parenting Questionnaire and Inventory of Attachment in Childhood and Adolescence. The one-factor structure of the KMSS was supported (CFA), and an invariance analysis showed the same structure for males and females. Preliminary evidence supported concurrent and discriminant validity, and high reliability (α=.97) was observed. In Study 2, the factor structure was replicated in an extended sample (361 couples) and invariance tests showed a similar one-factor structure for two stages of the family life cycle (children 6-12 and 13-18 years). Results indicated the measure’s suitability for research in the Portuguese context, however, further study is needed for its clinical use.
- Portuguese version of the Partner Support for Father Involvement Scale: Preliminary ValidationPublication . Antunes, Natália; Vieira-Santos, Salomé; Ribeiro, Maria Teresa; Roberto, Magda SofiaObjectives Partner support in the performance of the parenting role is critical, as it increases father involvement in the care of the child. However, the measures to assess this type of support are scarce. This study presents the preliminary validation of the Portuguese version of the Partner Support for Father Involvement (PSFI) scale (confirmatory factor analysis, measurement invariance models, reliability, and concurrent and discriminant validity). Methods The participants were 486 independent (unrelated) parents, 243 fathers (Mage = 42.13, SD = 5.57) and 243 mothers (Mage = 39.67, SD = 4.78), who completed the PSFI (translated version), the EMBU and the Co-parenting Questionnaire. Results Confirmatory factor analyses showed that the Portuguese PSFI had a three factor structure, in line with the original version of the scale (χ2 = 208.690, p < .001, CFI = .949, TLI = .931, SRMR = .040, RMSEA = .083, 90% CI [.072, .095]). An invariance analysis across mothers and fathers revealed the same structure for both. Cronbach’s alpha reliabilities were acceptable. Additionally, preliminary evidence of the scale’s concurrent and discriminant validity was found. Conclusions The results point to the suitability of the measure for the Portuguese population, namely in research contexts examining one partner’s perspective of the other partner’s involvement in parenting, and to its potential applicability for cross-cultural research. The measure will also be useful in clinical settings, namely as a tool in pre and post-intervention assessment, however further studies are needed to test this type of applicability.
