Engaging with the affiliative system through mindfulness: The impact of the different types of positive affect in psychosis

Abstract

Objectives: We aimed to explore associations between positive and negative symptoms, mindfulness, positive affect, and social safeness; and to understand the mediator role of positive emotions in the relationship between mindfulness and social safeness.Method: Fifty-six participants with a psychotic disorder were assessed with measures of mindfulness, negative and positive symptoms, positive affect, and social safeness.Results: All variables were associated with each other except for positive symptoms and active affect. Mindfulness predicted social safeness through safe affect, when controlling for positive and negative symptoms. Conclusions:This study contributes to knowledge of mechanisms behind social safeness adding the role of mindfulness and activation of positive emotions. The continuing study of mindfulness as an important mechanism for social safeness will allow further improvement of interventions for psychosis.

The Clinical Interview for Psychotic Disorders (CIPD): Preliminary results on interrater agreement, reliability and qualitative feedback

“…Each item ratings involve the clinical assessment of symptoms prominence, frequency and impact on and disruption to daily life (Kay, 1991). In a Portuguese sample of people with psychosis (n = 125), adequate psychometric properties were found, including Cronbach´s alphas of 0.79 for positive and 0.89 for negative symptoms (Martins et al, 2018). In the present study, the Cronbach´s alphas were 0.79 for positive symptoms and 0.81 for negative symptoms.…”

Transcultural adaptation and validation of the Korean version of the Types of Positive Affect Scale (TPAS): Application of the item response model

“…The TPAS has been widely used in studies of self-compassion [21], mindfulness [22], and parasympathetic activity [19]. However, few measures of positive affect are available in Asian languages, particularly Korean.…”

Southampton Mindfulness Questionnaire: Confirmatory Factor Analysis and Psychometric Properties Across Portuguese Clinical and Non-clinical Samples

“…Although few other studies have explored the psychometric properties of the SMQ, the adequate internal structure has been corroborated in different clinical and non-clinical samples (Chadwick et al, 2009;Martins et al, 2019;Perona-Garcelán et al, 2014;Wong & Chen, 2015). To our knowledge, only one study assessed temporal stability (1 week), and it was considered excellent in a sample of people with residual psychotic symptoms (Wong & Chen, 2015).…”
