To design a questionnaire to assess cognitive representations of mental health problems held by people diagnosed with schizophrenia.
Personal beliefs about health problems have been reliably associated with emotional and behavioural responses to those health problems and health outcomes. This area has been extensively explored in relation to physical health, but somewhat neglected in mental health. In this study, a questionnaire designed to assess key beliefs about physical illness (the Illness Perception Questionnaire - Revised) was modified for use in exploring beliefs about schizophrenia. The new measure was termed the Illness Perception Questionnaire for Schizophrenia (IPQS).
Participants were 124 people with a diagnosis of schizophrenia who completed the IPQS and additional measures to assess symptom severity, emotional state, and attitudes towards medication. The psychometric properties of the IPQS were analysed, including internal consistency, test-retest reliability, and discriminant and concurrent validity.
The IPQS subscales were shown to be internally reliable, and reliable over time. Correlations with measures of symptom severity, emotional state, and attitudes towards adherence to medication showed that the subscales were measuring the constructs that they were designed to measure.
The IPQS is a reliable and valid measure of cognitive representations of mental health problems held by people with a diagnosis of schizophrenia.
设计一份问卷，以评估被诊断为精神分裂症的患者对心理健康问题的认知表征。
个人对健康问题的信念已被可靠地证明与对这些健康问题的情绪和行为反应以及健康结果相关。这一领域在身体健康方面已得到广泛探索，但在心理健康方面有所忽视。在本研究中，一份旨在评估对身体疾病的关键信念的问卷（修订后的疾病认知问卷）被修改用于探索对精神分裂症的信念。新的测量工具被称为精神分裂症疾病认知问卷（IPQS）。
124名被诊断为精神分裂症的参与者完成了IPQS以及评估症状严重程度、情绪状态和对药物态度的其他测量工具。对IPQS的心理测量特性进行了分析，包括内部一致性、重测信度以及区分效度和同时效度。
IPQS分量表显示出内部可靠性，且随时间推移具有可靠性。与症状严重程度、情绪状态和对坚持服药态度的测量工具的相关性表明，这些分量表正在测量它们设计要测量的结构。
IPQS是一种可靠且有效的测量工具，用于评估被诊断为精神分裂症的患者对心理健康问题的认知表征。
