Abstract Repetitive negative thinking (RNT) is a transdiagnostic construct associated with a variety of emotional disorders. To date, disorder-specific self-report measures have been found to capture specific types of RNT. The Persistent and Intrusive Negative Thoughts Scale (PINTS) is a 5-item measure developed to overcome current limitations. The current study aims to translate and validate the PINTS for the Portuguese population. An online sample consisting of 432 participants (213 men, 219 women) completed the PINTS—PT and a set of related self-report measures. Confirmatory factor analysis revealed that the one-factor model fitted the Portuguese version and supported the proposed factorial structure.… [...]

Abstract The comparative clinical utility of the components of the psychological flexibility model of acceptance and commitment therapy (ACT) have not been equally evaluated. This study therefore conducted a feasibility and pilot two-arm dismantling trial by quarantining the self-as-context component. Sixteen participants were randomised to either 8 sessions of protocol-based ACT (Full-ACT) or 8 sessions of protocol-based ACT minus self-as-context (ACT-SAC). Process measures (flexibility and decentring) were taken at start of treatment, end of treatment, and at 6-week follow-up. Clinical outcome measures (functioning, anxiety, and depression) were collected on a session-by-session basis. Randomisation was well tolerated, all measures were completed,… [...]

Abstract Increasing interest in meta-cognitive and emotional acceptance-based therapies and using such therapies necessitate the development and validation of measures to assess cognitive and emotional constructs which underlie the assessment of therapeutic outcomes. This study examined the psychometric properties of the 28-item Leahy Emotional Schema Scale-II (LESS-II) in a large sample of Iranian university students. Six hundred and thirteen students completed the LESS-II, the Acceptance and Action Questionnaire-Second Version (AAQ-II), the Cognitive Emotion Regulation Questionnaire (CERQ), and the Metacognition Questionnaire-30 (MCQ-30). The results of both exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) showed that the 28-item LESS-II had… [...]
