Dimensions of well-being and their measurement: the SPF-IL scale

What are the dimensions of well-being? That is, what universal goals need to be realized by individuals in order to enhance their well-being? Social production function (SPF) theory asserts that the universal goals affection, behavioural confirmation, status, comfort and stimulation are the relevant dimensions of subjective well-being. Realization of these substantive goals and the perspective on opportunities to realize these goals in the future contributes to the affective and cognitive component of well-being. The theoretical elaboration of this theory has been published elsewhere. This paper provides a measurement instrument for the dimensions of well-being. To measure levels of affection, behavioural confirmation, status, comfort and stimulation and empirically validate the dimensions of well- being, the SPF-IL scale was developed.

Validation of the self-management ability scale (SMAS) and development and validation of a shorter scale (SMAS-S)

The 30-item Self-Management Ability Scale (SMAS) measures self-management abilities (SMA). Objectives of this study were to (1) validate the SMAS among older people shortly after hospitalisation and (2) shorten the SMAS while maintaining adequate validity and reliability. After eliminating 12 items, the confirmatory factor analyses revealed good indices of fit with the resulting 18-item SMAS (SMAS-S). The psychometric properties of both the SMAS and SMAS-S are good. The SMAS-S is a promising alternate instrument to evaluate self-management abilities.

Validation of the caregivers' satisfaction with Stroke Care Questionnaire: C-SASC hospital scale

To date, researchers have lacked a validated instrument to measure stroke caregivers' satisfaction with hospital care. We adjusted a validated patient version of satisfaction with hospital care for stroke caregivers and tested the 11-item caregivers' satisfaction with hospital care (C-SASC hospital scale) on caregivers of stroke patients admitted to nine stroke service facilities in the Netherlands. Stroke patients were identified through the stroke service facilities; caregivers were identified through the patients. We collected admission demographic data from the caregivers and gave them the C-SASC hospital scale. The C-SASC hospital scale is a promising instrument for measuring stroke caregivers' satisfaction with hospital stroke care.

Development and validation of a short version of the Assessment of Chronic Illness Care (ACIC) in Dutch Disease Management Programs

The main objectives of this study were to (1) validate the Assessment of Chronic Illness Care (ACIC) in the Netherlands in various Disease Management Programmes (DMPs) and (2) shorten the 34-item ACIC while maintaining adequate validity, reliability, and sensitivity to change. The Dutch version of the ACIC was tested in 22 DMPs with 218 professionals. We tested the instrument by means of structural equation modelling, and examined its validity, reliability and sensitivity to change. After eliminating 13 items, the confirmatory factor analyses revealed good indices of fit with the resulting 21-item ACIC (ACIC-S). The psychometric properties of the ACIC and the ACIC-S are good and the ACIC-S is a promising alternate instrument to assess chronic illness care.

Validation of the Patient Assessment of Chronic Illness Care (PACIC) and PACIC short version (PACIC-S) among cardiovascular disease patients in the Netherlands

The Chronic Care Model (CCM) has achieved widespread acceptance and reflects the core elements of patient-centred care in chronic diseases such as cardiovascular diseases (CVD). In the Netherlands the extent to which CVD patients receive care congruent with the CCM is unknown. The main objectives of this study were to validate the 20-item Patient Assessment of Chronic Illness Care (PACIC) and the 11-item (PACIC-S) in the Netherlands among CVD patients and investigate the validity, reliability, and sensitivity to change of both instruments. The psychometric properties of the Dutch PACIC and PACIC-S were satisfactory and it is sensitive to change, rendering it a valid and reliable instrument for assessing chronic illness care among CVD patients.

Development and Validation of the Older Patient Assessment of Chronic Illness Care (O-PACIC) Scale

Objectives of this study were to develop and validate an instrument to assess older patients’ experiences with integrated care delivery after hospitalization. Our study was conducted among older individuals (≥65) who had recently been discharged from a hospital. Point of departure for the development of the scale was the 20-item Patient Assessment of Chronic Illness Care (PACIC), which is proven to be a valid measure to assess chronically-ill patients’ assessment of integrated primary care delivery. After eliminating 10 items of the PACIC, the confirmatory factor analyses revealed good indices of fit with the 10-item Older Patient Assessment of Chronic Illness Care (O-PACIC) Scale. This study demonstrated that O-PACIC is a feasible, reliable and valid tool, with strong psychometric properties. The O-PACIC is a promising instrument to evaluate integrated care delivery after hospitalization among older patients.

Validation of the Dutch Aging Perceptions Questionnaire and development of a short version

Perceptions of aging have been found to independently contribute to various aspects of health and wellbeing in old age. Since valid and reliable perceptions of aging instruments are unavailable in Dutch, these associations have not yet been tested in the Netherlands. This study examined the reliability and construct validity of the Dutch-language version of the 7-dimension Aging Perceptions Questionnaire (APQ). Furthermore, in order to decrease the response burden, while retaining the APQ’s original factor structure, a short version of the APQ (APQ-S) was developed. Slotman, A., Cramm, J.M., Nieboer, A.P.
