This study refined the Support Needs Inventory for Parents of Asthmatic Children (SNIPAC) (Coleman, Maltby, Kristjanson, & Robinson, 2001) to produce a more parsimonious tool to assess the importance and meet the support needs of parents of children with asthma. The original tool was completed by 145 parents of 199 children with asthma, and 74 of these also provided test-retest responses. Internal consistency reliability, construct validity, and stability over time were assessed and refinements were made. Internal consistency reliability of the revised 20-item tool ranged from .77 to .95 for the three subscales of the Parent's Priority Scale (PPS), and .92 for the full PPS. Cronbach's alphas ranged from .74 to .90 for the three subscales of the Parent's Fulfillment Scale (PFS) and was .91 for the full scale. Factor analysis results of the PPS were compatible with the tool's conceptual framework. The revised 20-item tool demonstrated adequate psychometric properties in most areas. This tool may be used for research or clinical screening without imposing undue burden on parents. Further work is required to establish the tool's stability over time.
