Post-traumatic stress reactions among individuals with visual impairments: a systematic review

Abstract

Purpose: To conduct a systematic review of post-traumatic stress reactions among individuals with visual impairment (VI).

Materials and methods: Qualitative and quantitative studies were identified through searches in MEDLINE, EMBASE, PsycINFO, CINAHL, Web of Science, and Cochrane Libraries. The literature search was limited to humans, of English and Scandinavian languages and publication year between 1980 and 2017. Study quality was assessed for all the included studies and extracted data were synthesized using narrative analysis.

Results: Of 4235 records identified through literature search, eleven were included in the analyses. Results from the qualitative studies illustrated multiple physical, behavioral, emotional, and cognitive manifestations of trauma. Four out of five quantitative studies showed that various types of potentially traumatic events were significantly associated with mental health adversities (p < 0.05). The prevalence of post-traumatic mental disorders was 4–21.2% for depression, 0.9% for dysthymia, and 32% for substance misuse. The quality of the reviewed studies was considered low to moderate.

Conclusion: Traumatic experiences appear to have a great impact on the mental health in people with visual impairment (VI) and these results highlight their need for mental health care. Future studies with higher methodological rigor are recommended.

Implications for rehabilitation

• Visual impairment entails a greater susceptibility to some types of potentially traumatic events, especially threats in everyday life. This calls for a greater emphasis on safe community environments and universal design in public spaces.

• In rehabilitation after serious accidents or potentially traumatic events, professionals working with people with vision impairment should be aware of the different manifestations of post-traumatic stress responses and that some stress responses may cause additional disability.

• The high prevalence of traumatic events and their impact on mental health in individuals with visual impairments highlights a need of mental health care.
