Age Differences in Information Use While Making Decisions: Resource Limitations or Processing Differences?

Recent research on the decision-making abilities of older adults has shown that they use less information than young adults. One explanation ascribes this age difference to reductions in cognitive abilities with age. The article includes three experimental studies that focused on determining the conditions in which older and young adults would display dissimilar information processing characteristics. Findings from Studies 1 and 2 demonstrated that older adults are not necessarily at greater disadvantage than young adults in decision contexts that demand more information processing resources. Findings from Study 3 indicated that older adults when faced with decisions that require greater processing are likely to use a strategy that reduces the amount of information needed, whereas younger adults rely on strategies that utilize more resources. Combined the findings indicate that older adults change their decision-making strategies based on the context and information provided. Furthermore, support is provided for processing difference.

An Instrument to Measure Dental Students' Communication Skills With Patients in Six Specific Circumstances: An Exploratory Factor Analysis.

The aim of this study was to explore the internal structure of an instrument assessing dental students' confidence in their ability to communicate with patients in six specific circumstances (anxious, in pain, etc.) using exploratory factor analysis. In a Communication in the Dental Health Care Setting course at a U.S. dental school, second-year dental students in two years (2013 and 2014) responded to the six items on a survey instrument. Of the total 123 students, 122 fully completed the instrument, for a response rate of 99%. Analysis of the results identified a unidimensional scale with regards to patient-specific communication self-efficacy and explained 74% of the total variance. The scale had good internal consistency reflected by high Cronbach's alpha (α=0.929, 95% CI [0.907, 0.947]). These findings suggest the instrument may be a useful tool in assessing the development of patient communication skills in second-year dental students following a course in communication. Further exploration utilizing confirmatory analysis, determining predictive validity, and assessing convergent and discriminant evidence is warranted.

Gender differences in psychosocial responses to lung cancer.

BACKGROUND: Although biologically based sex differences in the smoking patterns, epidemiology, biomedical markers, and survival rates associated with lung cancer are well documented, examinations of psychosocial gender differences are scarce. OBJECTIVE: This cross-sectional study examined gender differences in psychosocial factors that are important in the medical management of lung cancer. METHODS: A convenience sample of patients who were attending a multidisciplinary lung cancer treatment center (Markey Cancer Center, Lexington, Kentucky) were invited to complete a psychosocial needs assessment. Eligibility criteria included primary diagnosis of lung cancer, age > or =18 years, and being cognitively intact. Measures focused on psychosocial resources, treatment decision-making, social consequences of treatments, and treatment outcomes. Data were collected between the fall of 2005 and the summer of 2006. RESULTS: A total of 47 women and 53 men (mean [SD] age, 62.81 [12.01] years; 95% white) completed the needs assessment. Gender was not found to be associated with demographic characteristics, time until diagnosis, treatment, or survival rate. Smoking histories differed significantly in the proportion of women and men who smoked or were former smokers (P = 0.01) as well as the age when they began to smoke (P = 0.02). There were no significant gender differences in social support networks, general coping, information needs, treatment decision satisfaction, functional health, life satisfaction, financial impact, or service needs. However, significant gender differences did indicate that women favored spiritual practices (P = 0.02) and religious coping (P = 0.04), and were more likely to endorse having a life mission (P = 0.03) and being part of a divine plan (P = 0.01). CONCLUSIONS: Previous research has found that religiousness and spirituality improved depressive symptoms and may ease end-of-life despair. In the present study of patients with lung cancer, gender differences in religiousness and spirituality suggest that this may be especially true for women, and that interventions should be directed toward their religious practices and coping.

The relationship between lung cancer patients' educational level and evaluation of their treatment information needs.

BACKGROUND: Understanding the information needs of lung cancer patients is critical to developing interventions to assist them with treatment decisions. The present study examined how educational level is related to lung cancer patients' perceptions of the importance of having their information needs met and how well those needs were met. METHODS: Lung cancer patients completed a needs assessment that evaluated treatment information needs, treatment decision satisfaction, coping, and life satisfaction. RESULTS: Results indicated that education did influence the importance ratings of information needs and influenced coping skills. CONCLUSIONS: Findings have implication for how doctors interact with well- and less-educated patients.

Gender differences in predictors of late-life health insurance knowledge.

For many older adults having access to affordable health care is a major concern. The present study's goal was to examine what factors were related to individuals' knowledge of late-life health insurance. A total of 131 women and 116 men (all aged 55-71) answered questions about private, Medicare, Medigap, and long-term care insurances. In addition, they answered demographic, personality, and health status questions. Results revealed that different factors are related to men's and women's knowledge of late-life health insurance options implying genderspecific educational interventions would be more effective than current educational interventions.

Evidence for an elders' advantage in the naive product usability judgments of older and younger adults.

OBJECTIVE: To determine whose naive judgments of consumer product usability are more accurate--those of younger or older adults. Accuracy is here defined as judgments compatible with results from performance-based usability tests. BACKGROUND: Older adults may be better able to predict usability problems than younger adults, making them particularly good participants in studies contributing to the user-centered design of products. This advantage, if present, may stem from older adults' motivation for more usable products or from their experience adapting their own environments to meet their changing physical, cognitive, and sensory needs. METHOD: Sixty older participants (ages 65-75 years) and 60 younger ones (ages 18-22 years) evaluated illustrations of consumer products on specific criteria (e.g., readability, learnability, or error rates). They either rated a single design for each product or ranked six alternative designs. They also explained their choices, indicated which features were most critical for usability, and selected usability-enhancing modifications. RESULTS: Although there was no reliable age difference in the amount of usability information provided in the open-ended explanations, older adults were more accurate at ranking alternative designs, selecting the most usability-critical features, and selecting usability-enhancing modifications (all ps < .05). CONCLUSION: The usability judgments of older adults are more accurate than those of younger adults when these judgments are solicited in a fixed-alternative, but not open-ended, format. APPLICATION: Because older adults are more discerning about potential product usability problems, they may be particularly valuable as research participants in early-stage design research (prior to the availability of working prototypes).
