Brief Description

The Satisfaction with Performance Scaled Questionnaire (SPSQ-46) is a 46-item self-report tool that assesses an individual’s level of satisfaction with their performance in daily living activities. The items are grouped into two primary subscales: (a) satisfaction with functionality and (b) satisfaction with performance in independent living skills.

Purpose

The purpose of the SPSQ-46 is to evaluate the degree of satisfaction a person experiences while performing everyday tasks. It is intended to identify areas that may require intervention or support, to assess functional capacity, and to monitor the effectiveness of therapeutic or support interventions over time.

Scoring Method

Participants rate only the activities they have performed in the last six months. They indicate how satisfied they were with their performance using a five-point scale derived from percentage frequency:
1 = not at all (0%),
2 = almost never (25%),
3 = sometimes (50%),
4 = more than half the time (75%),
5 = always (100%).
The first 24 items correspond to the functionality satisfaction subscale, and the remaining 22 to performance satisfaction. Average scores are calculated for each subscale, as well as an overall satisfaction index.

Validity

The SPSQ was developed and psychometrically validated in the United States. Research data confirm its conceptual validity, and factor analysis supports the existence of two distinct, interpretable subscales corresponding to the instrument’s design.

Reliability

The Greek version of the SPSQ-46 shows excellent reliability. Internal consistency indices (Cronbach’s alpha) were 0.97 for the performance satisfaction subscale and 0.93 for functionality satisfaction, indicating strong homogeneity and measurement stability.

Data Analysis and Use

Data can be analyzed by calculating average scores per item or per subscale. This analysis provides a detailed profile of satisfaction levels in different domains of daily living and is suitable for both research and clinical use. It can be used to monitor an individual’s progress over time or to compare groups with different levels of independence or support needs.
