To design a questionnaire to assess cognitive representations of mental health problems held by relatives of people diagnosed with schizophrenia.
The ways in which relatives respond to patients with a diagnosis of schizophrenia has been shown to impact on outcome. Understanding variation in relatives' responses is essential if successful interventions are to be developed. This study builds on previous research exploring attributions that relatives make about symptoms. The development of a new measure to assess beliefs that relatives have about schizophrenia is reported; The Illness Perception Questionnaire for Schizophrenia - Relatives version (IPQS-Relatives).
Sixty-two relatives completed the IPQS-Relatives, along with measures of general psychopathology, burden, appraisal of coping, and expressed emotion. The psychometric properties of the IPQS-Relatives were analysed, including internal consistency, test-retest reliability, and discriminant and concurrent validity.
IPQS-Relatives subscales were shown to be internally consistent and stable over time. Correlations with measures of general psychopathology, distress, burden, coping, and criticism indicate that the subscales have good concurrent validity.
The IPQS-Relatives can be used to assess relatives' beliefs about schizophrenia. This measure may aid family interventions that target beliefs associated with negative outcome for patients and their relatives.
设计一份问卷，以评估精神分裂症确诊患者亲属对心理健康问题的认知表征。
研究表明，亲属对精神分裂症诊断患者的反应方式会影响治疗结果。若要开发成功的干预措施，了解亲属反应的差异至关重要。本研究基于先前探索亲属对症状归因的研究。报告了一种评估亲属对精神分裂症信念的新测量工具；精神分裂症亲属版疾病认知问卷（IPQS-Relatives）。
62名亲属完成了IPQS-Relatives问卷，以及一般精神病理学、负担、应对评估和表达性情绪的测量。分析了IPQS-Relatives的心理测量特性，包括内部一致性、重测信度、区分效度和同时效度。
IPQS-Relatives分量表显示出内部一致性且随时间稳定。与一般精神病理学、痛苦、负担、应对和批评测量的相关性表明，这些分量表具有良好的同时效度。
IPQS-Relatives可用于评估亲属对精神分裂症的信念。该测量工具可能有助于针对与患者及其亲属负面结果相关信念的家庭干预。
