Abstract
This study of mothers of children in Pediatric Intensive Care Units (PICU) created two measures, (a) Health Related Family Boundary Ambiguity (HRFBA:PICU), (b) Maternal Caretaking Behavior (MCOS:PICU), and explored relationships between Health Related Family Boundary Ambiguity (HRFBA), Caretaking Behaviors, and Stress (STAI; Spielberger, et al., 1983).
In Phase I, 156 parents of children in 4 PICU's were recruited for psychometric evaluation of HRFBA:PICU. Thirteen likert-type scale items were developed from a grounded theory study of family uncertainty in PICU (Turner, Tomlinson & Harbaugh, 1990), building from Pauline Boss's Family Boundary Ambiguity construct (Boss & Greenberg, 1984). Internal consistency estimate (Cronbach's alpha) for the HRFBA:PICU was .81. Concurrent validity testing (n = 156) revealed significant positive relationships with Parent Stressor Scale: Parent Role Alteration Stress (PSS:PRAS) (Carter & Miles, 1982) and Mishel Illness Uncertainty Scale: Parent Child Form (MUIS:PCF) (Mishel, 1983). Construct validity testing (factor analysis) resulted in a 4 factor structure, with eigenvalues >1.00, accounting for 59% of the variance: Parental Affection and Protection, Parental Responsibilities and Rights, Parental Autonomy and Family Boundary Maintenance. Results of contrasted groups validity using a median split indicated HRFBA:PICU is sensitive to group differences in preparedness and child awareness, but not group differences in illness severity, nor number of PICU admissions. Results indicate sufficient reliability and validity for use of the HRFBA:PICU.
In Phase II, ethological methods were used to create the maternal caretaking observation schedule (MCOS:PICU). Seven mothers' video recordings were analyzed to develop an ethogram containing 24 maternal caretaking behavior codes. Codes were formatted into a time-interval recording instrument.
in Phase III, relationships among Caretaking Behaviors (MCOS:PICU), Stress (STAI), and HRFBA (HRFBA:PICU) were examined (n = 31). Results showed a positive relationship between Stress and HRFBA:PICU, but no significant relationships among Caretaking Behavior, Stress, and HRFBA. Multiple regressions were performed to examine the relative contributions of (a) wo Caretaking Behaviors, and (b) llness Severity and one Caretaking Behavior, respectively, on Stress and HRFBA (n = 31). Results indicated that neither Caretaking Behavior, nor Caretaking Behavior and Illness Severity combined, predicted Stress or HRFBA. Findings suggest nurses should use caution in relying on behaviors as indicators of psychological states.
