Description: This study developed and tested a Health-Oriented Interpersonal Nursing Actions Scale (H-OINAS) for home health care. The scale consists of 40 items in five subscales, tested by eight measures selectively administered to three independent convenience samples.

Preliminary assessment based on 20 graduate students' H-OINAS scores included item, subscale, and total scale analyses. Findings supported face validity, identified eight items that needed reexamination, and affirmed the H-OINAS's internal consistency, r =.96. Based on the findings four items were reworded and the verb form in four items was changed.

Six experts estimated the content validity of the H-OINAS. Content Validity Indexes were constructed by pairing (N = 15) the experts' item relevancy ratings. The proportion of items rated relevant by each pair ranged from.62 to.98. The proportion of interrater agreement on item relevancy ratings was K =.11. The experts' item to subscale assignments and the interrater agreement on the assignments, K =.31, did not support the representativeness of the 40 items in the H-OINAS.

Construct validity estimates were based on 222 home care nurses' H-OINAS scores and responses to a demographic questionnaire. A six factor solution emerged from unconstrained factor analysis and explained 66.6% of the score variance. Item loadings for the solution indicated that the H-OINAS measures a named construct, home health nursing care behavioral patterns, that synthesizes attributes of health, health-orientation and interpersonal nursing actions. ANCOVA revealed that years of home care experience (p. $<$.0059) contributed to score variance.

An estimate of concurrent validity based on a correlation, r =.25 (p. $<$.0005), of the nurses' scores on the H-OINAS and the Laffrey Health Conception Scale was compromised by conceptual differences in the two measures.

Coefficients of internal consistency were r =.97 for the scale and for the named six factors: establishing (r =.94), addressing (r =.90), acknowledging (r =.82), monitoring (r =.86), framing (r =.84) and facilitating (r =.85). Two-week test-retest coefficients of stability were r =.80 for the total scale and for the six named factors: r =.72, r =.69, r =.76, r =.71, r =.71, and r =.69 respectively.

There is evidence that the H-OINAS measures a construct, home health nursing care behavioral patterns, with sufficient validity and reliability to warrant its refinement.
