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.
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
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
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
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.
