“…The LEE is easy to administer and, according to the results of this study, the presence of the informal caregiver is not necessarily needed; administration to the patient may provide accurate and sufficient information. In the future, the expressed emotion of caregivers may be decreased with the use of motivational interviewing and the training of interaction skills to improve their strategies (Smeerdijk et al 2012 ). The number of contact hours with a patient might also be decreased for individual caregivers and/or the number of informal caregivers increased and, in such a manner, the burden on caregivers for the mentally ill be kept to a minimum.…”

ObjectiveTo identify and compare caregiver burden and expressed emotion (EE) in adult substance use disorder (SUD) patients with and without co-occurring attention deficit/hyperactivity disorder (ADHD) or autism spectrum disorder (ASD). To examine possible differences in correlations between caregiver burden and EE across patient groups.Design and MethodsCross-sectional study with measures of perceived burden (Involvement Evaluation Questionnaire: IEQ), subjective stress (General Health Questionnaire: GHQ) and perceptions of expressed emotion (Level of Expressed Emotion: LEE) in informal caregivers for patients with SUD, SUD+ADHD or SUD+ASD.FindingsNo differences in caregiver burden or expressed emotion when caregivers for patients with SUD were compared to caregivers for patients with SUD+ADHD. A moderate but non-significant difference for caregivers of patients with SUD versus SUD+ASD, which disappeared when the number of contact hours between patient and caregiver for the SUD only group was controlled for. The IEQ sum scores also substantially correlated with the LEE sum scores.ConclusionInformal caregivers for patients with only SUD show higher levels of burden and EE than informal caregivers for patients with SUD and a co-occurring ASD. This difference was largely explained by the higher number of contact hours between patient and caregiver in the SUD only group.

“…After the psycho-education, the parents received either FMI or RFS, which was scheduled every other week across a 6-month period. The content of the interventions has been described in detail elsewhere (Smeerdijk et al 2009, 2012). Here we provide a brief synopsis.…”

“…Therefore, we developed a family-based intervention for parents of young adults with recent-onset schizophrenia and co-occurring cannabis use; it involved training parents in interaction and motivational interviewing skills. In a RCT we demonstrated that this training, called Family Motivational Intervention (FMI), was significantly more effective than routine family support (RFS) in reducing quantity and frequency of patients’ cannabis use for at least 3 months after completion of the training (Smeerdijk et al 2012). The current study is an evaluation of the effectiveness of FMI at 15 months after the training had ended.…”

“…There was a significant decrease in self-reported number of days using cannabis, total grams used, and craving of cannabis observed between assessments at 3 months pre-treatment and 3 months post-treatment. However, there was no significant between-group difference in the proportion of negative urine tests at follow-up [38].…”

Schizophrenia I Psychosis I Cannabis use disorder I Psychosocial treatment I Pharmacological treatment Opinion statement Cannabis is used by more than 25 % of schizophrenia patients and is associated with symptom exacerbation and poorer clinical outcome. To date, evidence is scarce for treating cannabis use disorders among schizophrenia patients. Psychosocial interventions such as cognitive behavioral therapy, motivational interviewing, or contingency management have been evaluated as potential treatments for cannabis use disorders (CUD) among schizophrenia patients and in the general population. However, results are somewhat inconsistent, and efficacy appears to wane after treatment concludes. Pharmacotherapy has also been examined as a potential treatment for CUD but has not yet demonstrated consistent efficacy in the general population. The administration of second-generation antipsychotic medications is the pharmacological standard of care for schizophrenia as well as the treatment of choice for comorbid cannabis use among schizophrenia patients. Recent preliminary trials of pharmacotherapy agents in the general population must be further tested to confirm their potential efficacy at treating CUD. Based on the current evidence, we recommend a multi-faceted approach to treatment for CUD in the schizophrenia population, employing pharmacological and psychosocial modalities. We recommend using a second-generation antipsychotic medication; to date risperidone, olanzapine, and clozapine show the most promise for this population. We also recommend engaging patients in a combination of motivation-based treatment (motivational interviewing or motivation enhancement therapy) and cognitive behavioral treatment directed at cannabis use. When family systems allow, multidimensional family therapy should also be considered, particularly for adolescent patients. The available evidence suggests that CUDs will require ongoing treatment in order to maintain long-term efficacy.
