The Mobile Phone Affinity Scale: Enhancement and Refinement

Background

Existing instruments that assess individuals’ relationships with mobile phones tend to focus on negative constructs such as addiction or dependence, and appear to assume that high mobile phone use reflects pathology. Mobile phones can be beneficial for health behavior change, disease management, work productivity, and social connections, so there is a need for an instrument that provides a more balanced assessment of the various aspects of individuals’ relationships with mobile phones.

Objective

The purpose of this research was to develop, revise, and validate the Mobile Phone Affinity Scale, a multi-scale instrument designed to assess key factors associated with mobile phone use.

Methods

Participants (N=1058, mean age 33) were recruited from Amazon Mechanical Turk between March and April of 2016 to complete a survey that assessed participants’ mobile phone attitudes and use, anxious and depressive symptoms, and resilience.

Results

Confirmatory factor analysis supported a 6-factor model. The final measure consisted of 24 items, with 4 items on each of 6 factors: Connectedness, Productivity, Empowerment, Anxious Attachment, Addiction, and Continuous Use. The subscales demonstrated strong internal consistency (Cronbach alpha range=0.76-0.88, mean 0.83), and high item factor loadings (range=0.57-0.87, mean 0.75). Tests for validity further demonstrated support for the individual subscales.

Conclusions

Mobile phone affinity may have an important impact in the development and effectiveness of mobile health interventions, and continued research is needed to assess its predictive ability in health behavior change interventions delivered via mobile phones.

HIV testing is associated with increased knowledge and reductions in sexual risk behaviours among men in Cape Town, South Africa

HIV testing benefits those who test positive, allowing them to receive treatment, but the benefits for those who test negative remain controversial. We evaluated the impact of testing on HIV knowledge and sexual risk among men in South Africa. Men were recruited from townships outside Cape Town and completed a survey that assessed testing history, knowledge, and sexual behaviours. Among the 820 participants, 516 (63%) reported being tested (82% tested negative, 6% tested positive, and 12% unknown). Compared to those who had never been tested for HIV, men who tested for HIV were more knowledgeable about HIV transmission, but did not differ on sexual risk behaviour. Knowledge moderated the effect of testing on sexual risk such that men reported fewer sexual partners (incidence rate ratio (IRR) = 0.91, 95% CI = 0.84, 0.98) and fewer unprotected anal sex events (IRR = 0.81, 95% CI = 0.66, 1.00) if they had been tested for HIV and were knowledgeable about HIV transmission. For men testing HIV-negative, knowledge predicted fewer sexual risk behaviours. Previous HIV testing is associated with enhanced knowledge, which moderates sexual risk behaviour among South African men living in Cape Town. Results suggest that HIV testing may increase knowledge and lead to reductions in sexual risk even when results are negative.

Heart versus reason in condom use: implicit versus explicit attitudinal predictors of sexual behavior

We test the hypothesis that explicit and implicit measures of attitudes would differentially predict deliberate versus spontaneous behavior in the domain of condom use. Students completed explicit attitudinal and thought-listing measures about using condoms and implicit measures using attitude priming and Implicit Association Test (IAT) procedures. An attitude IAT measured the association between condom images and affective images; a self-identity IAT measured association of condoms with the self. We predicted and found that condom use with main partners was predicted by explicit measures but not implicit measures; the opposite was true for condom use with casual partners. Although the attitude priming measure was not positively correlated with casual condom use, the IATs were. The patterns of relations, however, were unexpectedly complex, due to a strong decrease in IAT effects over time, and different IATs assessing unique attitudinal dimensions.
