Is a program to improve grocery-shopping skills clinically effective in improving executive function and instrumental activities of daily living of patients with schizophrenia?

Occupational therapy interventions for adults with severe mental illness: a scoping review

“…In most studies (n=18), standard OT intervention or pharmacological treatment was performed in both the control and intervention groups. 20 23 24 26–28 30 32 33 40 42 44 47 48 50–53 However, in the intervention group, treatment was reinforced by specific OT interventions in SMI, including: a home-based rehabilitation programme, 20 a social cognition enhancement programme, 23 an OT programme focused on work reintegration, 24 a collaborative journal, 26 a computerised cognitive programme, 27 an emotion regulation skills programme, 28 a group programme for balance in ADL, 30 individualised OT, 32 dance therapy, 33 training in shopping skills, 40 activity-based OT, 42 OT narrative medicine, 44 weight loss psychiatric rehabilitation, 47 metacognitive training, 48 a prevocational programme, 50 a programme to reconnect patients with a significant activity, 51 an OT programme focused on expressive activities 52 and an early OT intervention. 53 …”

“… 22 45 49 In studies with both the control and intervention groups we found interventions such as an instrumental enrichment programme versus standard OT, 21 a programme focused on the management of the disease versus traditional OT, 25 a physical exercise programme versus traditional OT, 29 a metacognitive programme versus traditional OT, 31 a home-visit OT programme versus a management tool for daily life performance programme, 34 a recovery education programme versus traditional mental health treatment, 36 an aerobic dance programme versus a manual activities programme, 38 a balancing everyday life programme versus traditional OT, 41 a motivational intervention versus traditional OT 46 and a programme focused on executive functions versus a programme based on handmade activities. 54 In the included studies with a unique study group in which all participants were treated, we found interventions such as indoor and outdoor exercise programme, 37 a ‘therapeutic package’, 39 care as usual and cognitive–behavioural therapy 40 and a psychoeducation for schizophrenia programme. 43 Finally, three studies included three study groups to compare two different interventions with a control group: cognitive remediation therapy versus intensive OT versus healthy patients, 22 project activity group versus discussion group versus no treatment, 45 and OT at the community mental health centre (CMHC) versus OT at CMHC+psychosocial skill training versus outpatient follow-up.…”

“…The intervention programmes lasted between 3 and 9 months, and the sessions were mainly between 60 and 90 min long, although in three articles 40 42 45 the duration of the programme was notably shorter, lasting only 2 and 4 weeks. In turn, it should be noted that in three of the studies 26 30 41 only 1 weekly session was applied, while the rest 32 34 40 42 45 46 49 50 52 54 varied between 2 and 5 sessions per week.…”

Effectiveness of a Metacognitive Shopping Intervention for Adults with Intellectual Disability Secondary to Down Syndrome

“…A review of occupational therapy literature revealed no empirical studies investigating the effectiveness of interventions designed to improve shopping skills in adults with ID secondary to DS. However, the search did yield three occupational therapy studies examining shopping interventions for other clinical populations, including adults with schizophrenia (Kim et al, 2020), adolescents with autism spectrum disorder (Lamash & Josman, 2019), and children with learning disabilities (Karunakaran et al, 2018). All of the identified studies, regardless of the clinical population targeted, investigated the use of metacognitive strategy-training either in isolation or in combination with another targeted shopping intervention.…”

“…In the third study, Kim et al (2020) used a nonequivalent control group pretest-posttest design to investigate the effects of a grocery shopping intervention on executive function and IADL performance (e.g., shopping, financial management, meal preparation, medication management) in 20 adults with schizophrenia. They found that the participants who received the grocery shopping intervention, which consisted of practicing shopping strategies during real-life grocery shopping tasks, showed significantly greater improvements across both outcomes compared to the waitlist control group.…”
