Abstract

Background:

People with psychiatric disabilities often find it difficult to maintain a satisfactory occupational balance.

Aims/Objectives:

This study aimed to investigate the validity and reliability of the Turkish version of the Occupational Balance Questionnaire (OBQ11-T) in mental health.

Material And Methods:

OBQ11-T was applied to 149 people for construct validity analysis and to 61 of them for reliability analysis. Validity was determined using factor analyses. The reliability of the OBQ between the first and second evaluations was assessed using the intraclass correlation coefficient (ICC) for each item and the total OBQ11-T score. Internal consistency was assessed using Cronbach's alpha.

Results:

The results of factor analysis revealed one factor that explains 35.94% of the total variance in the model. OBQ11-T item 1 had the lowest and OBQ11-T item 4 had the highest factor loadings. The model fits the data according to the indices of relative fit (RMSEA = 0.087, CMIN/DF = 2.129, CFI = 0.901). There was an excellent correlation between test and retest OBQ11-T total scores (ICC = 0.905). All items of the OBQ11-T showed good reliability. Cronbach's alpha for the OBQ11-T total score was 0.839, indicating acceptable internal consistency.

Conclusions And Significance:

The current study showed that OBQ11-T is a valid and reliable tool for measuring the self-rated occupational balance of people with mental illness.

Self-Report Tests of Personality

Self-Report Tests of Personality

Self-report inventories are objective personality assessments that use multiple-choice items or numbered scales, typically ranging from 1 (strongly disagree) to 5 (strongly agree). They are often called Likert scales after Rensis Likert. These inventories are widely used due to their ease of administration and cost-effectiveness. One of the most prominent examples is the Minnesota Multiphasic Personality Inventory (MMPI), initially developed in the 1940s to assess abnormal personality traits.

Reliability and Validity

Reliability and Validity

Reliability and validity are two important considerations that must be made with any type of data collection. Reliability refers to the ability to consistently produce a given result. In the context of psychological research, this would mean that any instruments or tools used to collect data do so in consistent, reproducible ways.

Assessment of the Gastrointestinal System II: Health Perception Pattern

Assessing the gastrointestinal (GI) system is a complex process that begins with collecting subjective data. This data, collected through patient interviews, provides crucial insights into the patient's health history, perception patterns, and lifestyle habits, all contributing significantly to GI health.
Health Perception Patterns
Health perception patterns offer valuable insights into a patient's lifestyle habits and how they may impact their GI health. These patterns include:
