简要总结

The purpose of this study is to examine the effectiveness of family cognitive adaptation training, including its impact on functioning and caregiver burden. Families that receive the manual will be compared with a control group of families that will not receive the manual. The larger goal is to add to the tools family members have access to better support their family members with schizophrenia.

详细描述

Efforts to address the cognitive impacts of schizophrenia can be broadly defined as falling into either compensatory or restorative categories. Restorative interventions, such as cognitive remediation, have shown promise in reducing cognitive deficits and improving functional outcomes (McGurk et al., 2007). In contrast, compensatory approaches such as Cognitive Adaptation Training work around cognitive deficits by changing the client's natural environment to support improved functioning. These compensatory strategies serve to bypass cognitive deficits and negative symptoms by organizing belongings and creating reminders and environmental cues to support specific adaptive behaviors. An example includes the individual packaging of clothes to be worn by day, to simplify the process of choosing what to wear and decrease the likelihood of clients impulsively putting on too many clothes or otherwise dressing in a manner that is not a good fit for the climate or social settings (Draper et al., 2009; Maples & Velligan, 2008).

Cognitive Adaptation Training (CAT) is a manualized intervention that was developed to help individuals compensate for the cognitive deficits associated with schizophrenia. CAT interventions commence with a neuropsychological assessment of clients to determine the best profile of strategies to be implemented for the specific cognitive classification within which the person is placed. Interventions are based on two dimensions 1) level of executive functioning (as determined by scores on a set of neurocognitive tests) and 2) whether the behaviour of the individual is characterized more by apathy (poverty of speech and movement and difficulty initiating behaviours), disinhibition (distractibility and impulsivity) or a combination of the two. Clinicians then develop and implement an individualized set of strategies that address key domains such as hygiene, safety, dress, and medication. These strategies are then altered for strengths or weaknesses in the areas of attention, memory, and fine motor skills. For example, for someone with poor attention, the colour of signs can be changed regularly or florescent colours can be used to capture attention. For someone with memory problems (particularly those with good auditory attention) audiotapes can be used to sequence behaviour.

CAT interventions are established and maintained in the home during monthly to weekly visits from a CAT therapist/trainer with the intervention typically lasting 9 months in most of the trials that have taken place to date

Outcomes of randomized trials of CAT have been promising. Compared to control conditions, clients receiving CAT have lower levels of symptomatology, lower relapse rates, higher levels of adaptive functioning, better quality of life, and better medication adherence (Velligan et al., 2000; 2002; 2007; 2008a; 2008b). In general, CAT has been shown to be beneficial for individuals with schizophrenia who vary both in degree and type of functional impairment.

The support and involvement of family in the care of individuals with schizophrenia is both one of the most important contributors to wellness and recovery and is also, unfortunately, one of the least acknowledged components of the recovery process. A high proportion of persons with severe mental illness stay in touch with family and the involvement of family in care has been associated with better clinical outcomes, improved quality of life, and less use of hospitalization (e.g., Fischer et al., 2008). Despite evidence of the importance of family in the recovery process, the contribution of family is often not adequately appreciated by treatment providers, and contact with providers is often limited. Similarly under-developed are evidence-based tools to assist families in their efforts to support the recovery of their loved ones.

  • the key family member/support is actively involved in the support of the individual with schizophrenia and regularly visits them (i.e., once a week or more frequently) in their home environment
  • the individual being supported is identified (self-identified and identified by the family member) as having a primary diagnosis of schizophrenia
  • the individual with schizophrenia is not in crisis or experiencing other forms of instability (e.g., imminent loss of housing) per verbal report that would threaten the implementation of the manual strategies

结局指标

主要结局

Multnomah Community Ability Scale (MCAS)

时间窗: 4 months following baseline assessment

The Multnomah Community Ability Scale (MCAS; Barker et al., 1994) is a 17-item scale assessing functionality in four domains - health, adaptation, social skills and behaviour. Ratings are made on the basis of an interview with the patient and their family member. The MCAS generates a total score ranging from 17 to 85. Items on the MCAS are scored on a five-point scale. The four total domain scores ranges are - health, 5-25; adaptation, 3-15; social skills, 5-25; behaviour, 4-20. Lower ratings indicate less ability. Higher ratings usually mean an assessment of greater ability.

次要结局

  • Brief Adherence Rating Scale (BARS)(4 months following baseline assessment)
  • Satisfaction With Life Scale(4 months following baseline assessment)
  • Involvement Evaluation Questionnaire (IES)(4 months following baseline assessment)
