The association between substance use and the needs of patients with psychiatric disorder, levels of anxiety, and caregiving burden

The influence of substance use on patient's needs and caregiving consequences has received insufficient research attention. We sought to determine whether patients with comorbid substance use have higher levels of need, anxiety, depression, and caregiving consequences than those of patients who do not use substances. A total of 520 patients participated, and those who used substances (n = 216) reported higher levels of unmet needs, anxiety, and caregiving consequences than did patients who did not use substances. Carers of patients who used substances also reported higher anxiety and more caregiving consequences. Very few patients were actively involved in treatment programs to reduce their substance use.
