Reliability of internet- versus telephone-administered questionnaires in a diverse sample of smokers

Background

Smoking is more prevalent among lower-income individuals and certain racial/ethnic minorities. Addressing tobacco cessation among diverse populations is an urgent public health priority. As Internet use continues to rise among all segments of the US population, Web-based interventions have enormous potential to reach priority populations. Conducting Web-based smoking cessation research in priority populations requires psychometrically sound measurement instruments. To date, only one published study has examined the psychometric properties of Internet-administered measures commonly used in Web-based cessation trials. However, the sample was homogeneous with regard to race/ethnicity and income. We sought to replicate and extend these findings in a more diverse sample of smokers.

Objective

The aim was to examine the internal consistency and test-retest reliability of measures commonly used in smoking cessation clinical trials among racial/ethnic minorities and smokers with lower income.

Methods

Participants were enrolled in a randomized trial of the efficacy of an Internet smoking cessation program between June 2005 and September 2006. Following a baseline telephone assessment and randomization into the parent trial, participants were recruited to the reliability substudy. In phase I of recruitment, all participants in the parent trial were recruited to the substudy; in phase II, all consecutive racial/ethnic minority participants in the parent trial were recruited. Race and ethnicity were assessed via self-report using two standard items from the US Office of Management and Budget. An email was sent 2 days after the telephone assessment with a link to the Internet survey. Measures examined were quit methods, perceived stress, depression, social support, smoking temptations, alcohol use, perceived health status, and income. Internal consistency and test-retest reliability of Internet- versus telephone-administered measures were examined within four strata defined by race/ethnicity (non-Hispanic White, racial/ethnic minority) and annual household income (US $40,000 or less, more than $40,000).

Results

Of the 442 individuals invited, 319 participated (72% response rate): 52.4% were non-Hispanic White, 22.9% Black, 11.6% Hispanic, 7.8% Asian, 4.4% American Indian / Alaska Native, and 1% Native Hawaiian / Other Pacific Islander. About half (49.4%) reported an annual household income of US $40,000 or less, and 25.7% had a high school degree or less. Test-retest reliability was satisfactory to excellent across all strata for the majority of measures examined: 9 of 12 continuous variables had intraclass correlation coefficients ≥ 0.70, and 10 of 18 binary variables and both ordinal variables had kappa coefficients ≥ 0.70. Test-retest reliability of several quit methods varied across strata.

Conclusions

Race/ethnicity and income do not affect the psychometric properties of most Internet-administered measures examined. This knowledge adds to the confidence of conducting Web-based smoking cessation research and strengthens the scientific rigor of collecting information via the Internet on racial/ethnic minority and low-income subgroups.

Validating the Medical Data Interpretation Test in a Dutch population

Objective

To validate the Dutch translation of the Medical Data Interpretation Test.

Methods

A test–retest design with a 2-week interval was used.

Results

The intraclass correlation coefficient (ICC = .82), the limits-of-agreement interval (LOA = −8.96 to 2.48) and the test–retest reliability (Pearson's r = 86) suggest that the Dutch translation has good reproducibility. Construct validity was tested by two hypotheses, both of which were confirmed. University participants had higher test scores than non-university participants (p = .02), and males did not score differently than females (p = .61).

Conclusion

The results suggest that the Dutch version of the Medical Data Interpretation Test is an adequate scale to assess ability to interpret medical data.

Practice implications

Assessing patients’ numeracy skills before a counseling session will enable the counselor to adjust subsequent communication accordingly and, as such, improve the session's effectiveness.     

Validation of the Norwegian version of MAPPIN’SDM,an observation-based instrument to measure shared decision-making in clinical encounters

ObjectiveTo validate the Norwegian version of MAPPIN’SDM observer scales with regard to reliability, accuracy and the extent to which the scales include the essentials of the shared decision-making concept.MethodsThree MAPPIN’SDM scales, focusing on the skills of doctor, patient and dyad, were applied to audiovisual records of 35 decision sequences. Inter-rater reliabilities were determined based on kappa coefficients. Sensitivities and specificities were calculated with regard to an expert reference standard. Convergent validities were calculated with the OPTION₅ scale. MAPPIN’SDM was qualitatively compared to OPTION5 using Makoul & Clayman’s Integrative Model structure.ResultsInter-rater reliabilities were high on average over 11 items in each of three observer scales (MAPPIN_doctor = 0.77, MAPPINpatient = 0.82, MAPPIN_dyad = 0.77). Patient involvement was detected accurately (MAPPIN_dyad: mean sensitivity/specificity 93/91%). Comparison with OPTION₅ showed weak to moderate correlation (Spearman’s ρ/p-value: MAPPIN_doctor: = 0.44/0.009, MAPPIN_patient: 0.38/0.024, MAPPIN_dyad 0.40/0.016) and little content overlap.ConclusionMAPPIN’SDM_norge is capable of assessing SDM highly reliably and accurately. Divergence from OPTION₅ reflects explicit disagreement regarding the concept’s assumptions.Practice implicationsMAPPIN’SDM_norge is ready for use in Norway. In-depth debate on the SDM concept’s essentials is urgently needed.
