The potential role of positive aspects of caregiving in enhancing caregivers' health is an important issue. The aim of this study was to develop and validate Positive Aspects of Caregiving Questionnaire (PACQ) in caregivers of patients with dementia in Iran.
Content validation process was used to content valid development. Cronbach α and intraclass correlation coefficient (ICC) were calculated as reliability indices. We used exploratory factor analysis to extract potential latent factors and evaluate the factor structure of PACQ. We assess correlation between PACQ and caregiver burden for divergent validity. For convergent validity, correlation between PACQ and self-rated health was specified.
Content validity indices (CVIs), internal consistency, and test-retest reliability were CVI > 0.80, α = 0.785, and ICC = 0.905, respectively. Moreover, item-total correlations confirmed good reliability of PACQ. Two factors were identified by factor analysis in this 10-item measure: patient and caregiver relationship and caregiver's psychological well-being. Divergent validity and convergent validity were established by high negative correlation between positive aspect of caregiving (PAC) and caregiver burden along with significant positive correlation between PAC and self-rated health, respectively. While Cronbach α for the entire scale was 0.785, Cronbach αs for both of the scale components were 0.71.
The PACQ demonstrated acceptable psychometric properties of reliability and performs well in preliminary tests of validity as a measure of positive aspects of caregiving. This measure can be used to determine the outcome of interventional programs on positive, not only negative, aspect of caregiving.
护理积极方面在促进护理人员健康中的潜在作用是一个重要问题。本研究的目的是开发并验证伊朗痴呆症患者护理人员的护理积极方面问卷（PACQ）。
采用内容效度法进行内容效度开发。计算克朗巴哈α系数和组内相关系数（ICC）作为信度指标。我们使用探索性因素分析来提取潜在的潜在因素并评估PACQ的因素结构。我们评估PACQ与护理人员负担之间的相关性以检验区分效度。对于聚合效度，指定了PACQ与自评健康之间的相关性。
内容效度指数（CVI）、内部一致性和重测信度分别为CVI>0.80、α = 0.785和ICC = 0.905。此外，项目-总分相关性证实了PACQ具有良好的信度。在这个10项量表中，通过因素分析确定了两个因素：患者与护理人员的关系以及护理人员的心理健康。护理积极方面（PAC）与护理人员负担之间的高负相关以及PAC与自评健康之间的显著正相关分别确立了区分效度和聚合效度。虽然整个量表的克朗巴哈α系数为0.785，但两个量表分量表的克朗巴哈α系数均为0.71。
PACQ表现出可接受的信度心理测量特性，并且在作为护理积极方面测量的效度初步测试中表现良好。该测量方法可用于确定干预项目在护理积极而非消极方面的结果。
