Cognitive appraisal and depression in cancer patients undergoing chemotherapy: mediation by perceived stress and self-efficacy

Dyadic effects of perceived stress, relationship satisfaction and distress disclosure on emotional distress in colorectal cancer patients and their family caregivers: An actor-partner interdependence mediation model

Objective

This study adopted a dyadic analysis method to examine the effect of perceived stress on emotional distress and determine whether relationship satisfaction and distress disclosure act as mediators in colorectal cancer (CRC) enterostomy patient-caregiver dyads.

Methods

A total of 312 patient-caregiver dyads completed measures assessing perceived stress, relationship satisfaction, distress disclosure, and emotional distress. The data were analyzed using the actor-partner interdependence mediation model.

Results

This study found that the perceived stress of patients and caregivers both had direct and indirect actor effects on emotional distress (through relationship satisfaction). Another important finding is that perceived stress had indirect actor-partner effects (through distress disclosure) on emotional distress.

Conclusions

This study highlights that perceived stress, relationship satisfaction, and distress disclosure of patients and their caregivers are key factors that can be considered for improving emotional distress. It also partially confirmed the interdependence of patients with CRC and their caregivers.

The association between family adaptability and adolescent depression: the chain mediating role of social support and self-efficacy

Objective

Previous research has shown a correlation between family adaptability and adolescent depression. However, there is a lack of studies that have investigated the underlying mechanism between family adaptability and adolescent depression. Based on the Ecological Systems Theory, this study aims to investigate the link between family adaptability and depression in adolescents, mediated by the sequential roles of social support and self-efficacy.

Methods

The sample consisted of 1086 students randomly selected from seven public middle schools in Shandong Province, Eastern China. All the participants filled in the structured self-report questionnaires on family adaptability, social support, self-efficacy, and depression. The data were analyzed using SPSS 25.0 and Structural Equation Modeling (SEM) in AMOS 24.0.

Results

The findings of this study are as follows: (1) Family adaptability is negatively associated with adolescent depression; (2) Social support plays a mediating role between family adaptability and adolescent depression; (3) Self-efficacy plays a mediating role between family adaptability and adolescent depression; (4) Social support and self-efficacy play a chain mediation role between family adaptability and adolescent depression.

Conclusion

It is suggested that early interventions and support should be provided to facilitate adolescents' family adaptability, social support, and self-efficacy, thus reducing their depression and improving mental health of adolescents.
