This systematic review addresses how adolescent-rated parent-child communication (PCC) quality is related to adolescent mental health. We performed a systematic literature search in Medline and APA PsycInfo, including peer-reviewed quantitative studies examining associations between adolescent-rated dyadic PCC quality and general as well as specific measures of adolescent mental health. Qualitative and case studies were excluded, as were studies reporting only parent-rated communication quality or instruments assessing other constructs than dyadic PCC. We screened 5314 articles, of which 37 were included in the review. We assessed study quality with the Mixed Methods Appraisal Tool. We synthesized the findings in a table and narratively, reporting the main outcomes organized according to mental health constructs. The included studies were mainly cross-sectional. The results showed that adolescent-rated PCC quality is negatively associated with mental health constructs, demonstrating small to large effects across different mental health constructs and populations. The associations were found for general mental health and specific domains, including depression, anxiety, psychosis, suicidal ideation, post-traumatic stress symptoms, and addictive internet use/gaming. The findings demonstrate that PCC is a relevant variable to consider in assessing adolescent mental health and preventive efforts. Limitations include the exclusive focus on adolescent-reported PCC questionnaires since parent- and observer-rated instruments may lead to different results. Also, PCC is related to other constructs, such as dyadic relationships, that were not included in this review. We conclude that PCC is a relevant variable to consider in mental health research. Our findings suggest that PCC may be considered in mental health practice, both in terms of assessing its quality and potentially by tailoring interventions to enhance PCC. These may represent a mean to promote adolescent mental health.
