Occupational Performance History Interview – Version 2.1 (OPHI-2.1)

Description

The Occupational Performance History Interview – Version 2.1 (OPHI-2.1) is an assessment tool used to collect detailed information regarding an individual’s occupational history, daily activities, life experiences, and occupational performance.

The revised version (OPHI-2.1) represents an updated form of the original instrument, incorporating improvements and refinements aimed at providing a more comprehensive evaluation of occupational performance and its relationship with everyday life.

The tool is primarily used within occupational therapy and rehabilitation settings to understand how personal experiences, environmental conditions, and occupational activities influence an individual’s functioning and quality of life.

Data Analysis and Use

The OPHI-2.1 is based on a structured interview process in which the evaluator collects qualitative and descriptive information about the individual’s occupational experiences.

The interviewer asks participants to describe and analyze their occupational experiences, personal perceptions, and the impact of activities on their daily life.

The information obtained from the interview is used to better understand the individual’s needs and to design appropriate interventions aimed at improving occupational performance and quality of life.

The collected data may be analyzed qualitatively through interpretation of occupational patterns, life experiences, strengths, difficulties, and contextual factors affecting participation.

Objective

The primary objective of the OPHI-2.1 is to understand how occupational activities, personal experiences, and life circumstances influence an individual’s occupational performance and well-being.

The instrument aims to provide a comprehensive understanding of the individual’s occupational history and identify factors that support or limit effective participation in everyday activities.

Structure and Content

The OPHI-2.1 focuses on the individual’s occupational history and includes information related to:

Occupational experiences throughout life.

Daily activities and participation patterns.

Personal perceptions regarding occupational performance.

The influence of environmental and life conditions on occupational functioning.

Through the interview process, the tool provides a holistic view of the relationship between occupation, personal identity, and quality of life.

Scoring

The available document describes the OPHI-2.1 primarily as an interview-based assessment method and does not provide specific scoring procedures or numerical interpretation criteria.

The results are derived from the analysis of the individual’s occupational history, experiences, and reported difficulties, supporting clinical interpretation and intervention planning.

Statistical Analysis

The OPHI-2.1 is primarily a qualitative assessment instrument; therefore, analysis focuses mainly on the interpretation of interview information rather than traditional quantitative scoring.

When used in research contexts, statistical procedures may include evaluation of reliability, validity, inter-rater agreement, and relationships between occupational performance characteristics and other functional measures.

Validity

The validity of the OPHI-2.1 is supported by its theoretical foundation within occupational therapy and the Model of Human Occupation (MOHO) framework.

The instrument evaluates meaningful aspects of occupational functioning by considering the interaction between personal experiences, activities, and environmental conditions.

Reliability

The available document does not provide specific reliability coefficients for OPHI-2.1, such as Cronbach’s alpha or test–retest reliability values.

Reliability assessment of the instrument has traditionally focused on consistency of administration, agreement between evaluators, and the structured interpretation of occupational history information.
