Phase II: Pilot-planning Phase (year 2)

Goals of this phase: To continue with the instrument development process and to negotiate with research sites. During this phase, Subject Matter Experts recommended additional versions of the JPQ to accommodate important populations that were not initially included in the research.

Progress, Phase II

• The psychometric properties of the JPQ were investigated. This included the pilot-testing of the JPQ in the SPMI population. Internal consistency of scales and co-variation of model linkages were examined.

• A validation study was conducted and analyzed, using the JPQ and the JDS. Scale reliabilities and inter-scale correlations between the two instruments were calculated.

• These investigations provided overall support for the psychometric properties of the JPQ and informed revisions to the instrument. Items were added to key scales and some problematic (e.g., reflected) items were reworded.

• The JPQ was also expanded to include numerous constructs identified in the qualitative research as important to the SPMI population. Additions to the model are shown in Table 1.

• The revised JPQ was pilot-tested and re-analyzed for psychometric properties.

• Individual JPQ feedback reports were developed to increase utility and to provide participants with the greatest possible benefits for participating in the study.

• A pilot test was conducted for the Service Provider Version of the JPQ at the National Association of Case Management Conference. This version was created primarily for use in training case management and vocational rehabilitation staff in how to a) administer the JPQ and b) interpret and discuss JPQ results with consumers.

• A JPQ Preview Version was constructed for consumers who have never worked, or have not worked within the past six months. The addition of this version allows data to be collected during the entry phase of the consumer to vocational programming. Items were rewritten to apply to individuals with no or limited work history. The companion Staff Version was also created for the Preview Version.

• Numerous field experts requested variations of the three versions of the JPQ for use with the population of economically disadvantaged adults (e.g., welfare clients). Subject matter experts expect that a noteworthy proportion of this population suffers from an undiagnosed but significant mental illness. All versions of the JPQ were revised for this population by eliminating items that blatantly refer to mental health issues. Two multi-item scales were added including ODMH's Symptom Distress scale and a Coping Scale designed to reflect the Mental Health Confidence Questionnaire.

• Pilot testing of the JPQ Preview version for both the SPMI and economically challenged populations occurred in Lucas County. Preliminary analyses suggest that the majority of scales possess adequate internal consistency. Analyses will continue as additional cases are received.

• Table 2 shows a complete listing of the eleven JPQ versions and forms. Note that on any given form of the JPQ, only those constructs are represented that make sense for that population. If a construct does not make sense for a particular population, that scale was dropped for that version or form.

• An alternative to paper-based JPQ data collection and feedback is in the process of development. Software will enable computer administration of the JPQ. This enhancement increases the feasibility of use of the JPQ by eliminating third-party data entry and by providing immediate feedback to the consumer and mental health or vocational rehabilitation staff.
