          Abstract

          Purpose

          The purpose of this study is to assess the psychometric properties of the Dutch version of the 34-item Short-Form Supportive Care Needs Survey (SCNS-SF34) and the newly developed module for head and neck cancer (HNC) patients (SCNS-HNC).

          Methods

          HNC patients were included from two cross-sectional studies. Content validity of the SCNS-HNC was analysed by examining redundancy and completeness of items. Factor structure was assessed using confirmatory and exploratory factor analyses. Cronbach’s alpha, Spearman’s correlation, Mann–Whitney U test, Kruskall–Wallis and intraclass correlation coefficients (ICC) were used to assess internal consistency, construct validity and test–retest reliability.

          Results

          Content validity of the SCNS-HNC was good, although some HNC topics were missing. For the SCNS-SF34, a four-factor structure was found, namely physical and daily living, psychological, sexuality and health system and information and patient support (alpha = .79 to .95). For the SCNS-HNC, a two-factor structure was found, namely HNC-specific functioning and lifestyle (alpha = .89 and .60). Respectively, 96 and 89 % of the hypothesised correlations between the SCNS-SF34 or SCNS-HNC and other patient-reported outcome measures were found; 57 and 67 % also showed the hypothesised magnitude of correlation. The SCNS-SF34 domains discriminated between treatment procedure (physical and daily living p = .02 and psychological p = .01) and time since treatment (health system, information and patient support p = .02). Test–retest reliability of SCNS-SF34 domains and HNC-specific functioning domain was above .70 (ICC = .74 to .83), and ICC = .67 for the lifestyle domain. Floor effects ranged from 21.1 to 70.9 %.

          Conclusions

          The SCNS-SF34 and SCNS-HNC are valid and reliable instruments to evaluate the need for supportive care among (Dutch) HNC patients.

            Brief assessment of adult cancer patients' perceived needs: development and validation of the 34-item Supportive Care Needs Survey (SCNS-SF34).

            This study aimed to develop and validate a short version of the Supportive Care Needs Survey (SCNS) that would reduce respondent burden and could be used in routine cancer care, without compromising the psychometric properties of the original instrument. Secondary analyses of the data from two studies (n = 888 and 250) were undertaken. All 59 items of the original SCNS were assessed using psychometric analyses and evaluated for clinical utility. The 34 items retained were examined for internal consistency, ceiling and floor effects, known groups validity, convergent validity, sensitivity and readability. The 34-item instrument has five factors (psychological, health system and information, physical and daily living, patient care and support, and sexuality needs) identical to the original instrument, explaining 73% of the variance. Internal consistency was high with Cronbach's alpha coefficients for the five factors ranging from 0.86 to 0.96. Correlations of the 34-item short-form SCNS (SCNS-SF34) with three other measures of psychosocial well-being demonstrated convergent validity (r = 0.48-0.56). Kappa coefficients of at least 0.83 for each domain indicated almost perfect agreement between the 34-item and 59-item surveys to identify patients needing help. The 34-item SCNS maintained the psychometric properties of the original instrument and could be readily comprehended by people with seventh to eighth grade education. The SCNS-SF34 is a valid instrument for measuring cancer patients' perceived needs across a range of domains, and could be utilized as part of routine cancer care.

              Supportive care framework.

              The Supportive Care Framework for Cancer Care was originally formulated in 1994 (Fitch, 1994). The framework was designed as a tool for cancer care professionals and program managers to conceptualize what type of help cancer patients might require and how planning for service delivery might be approached. The framework has been presented in various arenas and the number of requests has been growing for a wider distribution of a full description of the framework. The purpose of this article is to share the Supportive Care Framework for Cancer Care with the cancer nursing community. As a conceptual framework, it may be a useful tool for service or program planning, a basis to organize educational approaches in cancer care, or as a model underpinning research projects.
