Effectiveness of internet-based psychosocial interventions on psychological distress, expressed emotion, and knowledge about psychosis among family caregivers of people with schizophrenia: a systematic review protocol

Abstract

Objective: The objective of this review is to evaluate the effectiveness of internet-based psychosocial interventions versus active comparators (such as in-person interventions, bibliotherapy, or telephone interventions) and passive comparators (such as usual psychiatric care) on psychological distress, expressed emotion, and knowledge about psychosis in family caregivers of people with schizophrenia. Introduction: Family caregivers of individuals with schizophrenia are at increased risk of developing mental disorders. Despite the widespread dissemination of reliable guidelines for caring for people with schizophrenia and their family caregivers, these have been poorly implemented. Hence, internet-based interventions with caregivers of people with schizophrenia could be an effective and feasible option. Inclusion criteria: This review will include studies focusing on the family caregivers of individuals diagnosed with schizophrenia. Internet-based psychosocial interventions will be defined as any psychosocial intervention that is internet-based compared with active comparators (such as in-person interventions, bibliotherapy, or telephone interventions) and passive comparators (such as usual psychiatric care). The primary outcomes of this review will include psychological distress, expressed emotion, and knowledge about the psychosis of family caregivers of people with schizophrenia. The secondary outcome will be the hospitalization of people with schizophrenia. Methods: MEDLINE (PubMed), CINAHL (Ovid), Scopus, Cochrane Library, and ProQuest Dissertations and Theses will be systematically searched for published and unpublished studies from 2010 in English and Thai. Two reviewers will select studies, critically appraise them, and perform data extraction independently. Finally, when possible, the studies will be pooled through statistical meta-analysis and grading of the certainty of evidence by each outcome.
