The Role of Human Voice in Direct-To-Consumer Health Communication.

Despite overall positive perceptions, many customers distrust direct-to-consumer genetic testing companies in regard to privacy and aftercare. Prior research suggests companies can assuage mistrust by personalizing communication when discussing sensitive health information. This content analysis of customer e-mails (N = 338) investigates the purpose, personalization, and use of the human voice strategy by direct-to-consumer genetic testing companies to gain trust. Results reveal that companies rarely use human voice when communicating with customers, most of the information provided is promotional, and they invite dialogue less over time. Theoretical and practical implications are provided.

How message appeals and prior product use influence information processing, risk perceptions, trust, attitudes, and genetic test purchase intentions.

Within the direct-to-consumer (DTC) genetic test industry, attracting customers can be difficult especially due to the highly sensitive nature of these products. How these tests are communicated to consumers may be one avenue in which companies can impact customer purchase intentions. A 2 (message sidedness: one-way vs. two-way refutational) x 2 (hedging: present vs. absent) between-subjects experiment was conducted to understand how message features and prior product use influence information processing, risk and trust perceptions, and attitude toward the genetic test, which in turn, may influence direct-to-consumer (DTC) genetic test purchase intentions. Results demonstrated that having used a genetic test in the past predicted participants' trust in the company, information processing, and risk judgments; however, among those who used a genetic test, viewing a message that included hedging tended to increase their trust in the message. Trust in the message and company, information processing, and risk judgments significantly predicted participants' attitudes toward genetic testing, which in turn predicted their purchase intentions. The results suggest that in the context of DTC genetic test messaging, practitioners should strive to increase consumer trust in the message and the company and facilitate information processing, and they should work to diminish perceived risk. These results suggest opportunities for identifying other message features that may influence message and company trust, information processing, risk judgments, and attitudes related to DTC genetic testing.

The influence of depression on treatment for methamphetamine use.

OBJECTIVE: To determine whether the presence of comorbid depression influences response to psychological treatment for methamphetamine use. DESIGN: Randomised controlled clinical trial. SETTING AND PARTICIPANTS: Our study was conducted between 2001 and 2005 at two sites in Australia: the Hunter Region of New South Wales and the city of Brisbane, Queensland. The 214 participants, who were all using methamphetamine at least once a week in the month prior to the study, were self-referred or referred from health services or drug and alcohol clinical services. Participants were divided into two groups based on whether or not they had depressive symptoms at baseline. INTERVENTIONS: The control group received only a self-help booklet; the two treatment groups received either two or four counselling sessions involving cognitive behaviour therapy and motivational interviewing techniques to manage methamphetamine use. MAIN OUTCOME MEASURES: Changes in methamphetamine use and depression at 5 weeks and 6 months after baseline. RESULTS: Over 70% of participants met criteria for depression at baseline, and depression was associated with significantly greater severity of methamphetamine use and related issues. Benzodiazepine use was significantly higher among depressed than non-depressed participants. Reductions in methamphetamine use between baseline and 5 weeks were independently predicted by comorbid depression, in favour of increased change among those with baseline depression. Depressed participants who received three or four counselling sessions showed a significant reduction in depression at 5 weeks. However, reductions in methamphetamine use and depression compared with baseline were no longer evident at 6 months. CONCLUSIONS: Over the short term, comorbid depression did not negatively affect response to treatment, with some evidence of a dose-response treatment effect for reduction in depression. This was not maintained at 6 months, indicating that methamphetamine-focused treatment may not enable people with comorbid depression to make sustained improvement at the level of their counterparts without depression.

Major depression among methamphetamine users entering drug treatment programs.

OBJECTIVE: To determine the prevalence of major depression among people entering treatment for methamphetamine use. DESIGN, SETTING AND PARTICIPANTS: The study was a cross-sectional survey involving 41 specialised drug and alcohol treatment agencies in Brisbane and Sydney. Services provided by these agencies included residential rehabilitation, detoxification and counselling. Participants were 400 people entering treatment for methamphetamine use who were recruited from participating treatment agencies between January 2006 and November 2007. Participants underwent a structured, face-to-face, 1.5-hour interview. Assessment instruments included the Composite International Diagnostic Interview and the Short Form 12. MAIN OUTCOME MEASURE: Diagnosis of a major depressive episode in the year prior to the study. RESULTS: The prevalence of major depression in the year prior to the study was 40% (95% CI, 35%-44%). A noteworthy post-hoc observation was that a further 44% of participants met the symptom criteria for major depression but were excluded from a diagnosis because their symptoms were better accounted for by psychoactive substance use. Both major depression and these latter cases of "substance-induced depression" were associated with severe symptoms of depression, high levels of disability and suicidal ideation. CONCLUSION: Most people entering treatment programs for methamphetamine use have levels of depression that require clinical management. Making a diagnosis of major depression in the context of heavy methamphetamine use is problematic because of substance-induced symptoms of depression.

Testing how different narrative perspectives achieve communication objectives and goals in online natural science videos.

Communication of science through online media has become a primary means of disseminating and connecting science with a public audience. However, online media can come in many forms and stories of scientific discovery can be told by many individuals. We tested whether the relationship of a spokesperson to the science story being told (i.e., the narrative perspective) influences how people react and respond to online science media. We created five video stimuli that fell into three treatments: a scientist presenting their own research (male or female), a third-party summarizing research (male or female), and an infographic-like video with no on-screen presenter. Each of these videos presented the same fabricated science story about the discovery of a new ant species (Formicidae). We used Qualtrics to administer and obtain survey responses from 515 participants (~100 per video). Participants were randomly assigned to one of the videos and after viewing the stimulus answered questions assessing their perceptions of the video (trustworthiness and enjoyment), the spokesperson (trustworthiness and competence), scientists in general (competence and warmth), and attitudes towards the research topic and funding. Participants were also asked to recall what they had seen and heard. We determined that when participants watched a video in which a scientist presented their own research, participants perceived the spokesperson as having more expertise than a third-party presenter, and as more trustworthy and having more expertise than the no-spokesperson stimuli. Viewing a scientist presenting their own work also humanized the research, with participants more often including a person in their answer to the recall question. Overall, manipulating the narrative perspective of the source of a single online video communication effort is effective at impacting immediate objective outcomes related to spokesperson perceptions, but whether those objectives can positively influence long-term goals requires more investigation.

Maternal and perinatal outcomes of indicated inductions of labor.

PURPOSE: The purpose of this study was to evaluate the labor characteristics and maternal/perinatal consequences following indicated induction of labor. METHODS: This retrospective study examined all of the indicated inductions over 24 months and at two institutions evaluated mode of delivery (vaginal versus cesarean) as well as a comprehensive list of labor characteristics and maternal/perinatal outcomes. RESULTS: There were 1577 indicated inductions with 1097/1577 (69.6%) delivering vaginally. Women with a cesarean delivery had lower parity (p < (0).0001) and Bishop's score (p < (0).0001), and higher body mass indices (p = 0.022). Indication for induction due to preeclampsia increased the risk of a cesarean delivery (p = 0.008). Chorioamnionitis, post-partum complications and NICU admissions were greater in the women delivered by cesarean section. CONCLUSIONS: Indicated inductions which result in cesarean delivery were more likely in women with higher body mass indexes, lower parity, and Bishops scores, as well as preeclampsia.
