Older men are an under-researched population in Counselling Psychology. This thesis explores how older men in sobriety experience their emotions in therapy and aims to understand the meaning of these experiences from a psychologically gendered subject perspective. Semi-structured interviews were carried out with six older men (aged 62 and above) and interview transcripts were analysed using Interpretative Phenomenological Analysis (IPA), a qualitative methodology that focuses on the lived experience and the meaning people give to these experiences. The analysis highlighted significant challenges for older men when attempting to unlock, process or discuss emotions in therapy. The analysis also revealed positive transformational effects by those who were able to transcend the confines of gendered constructs with concerted emotional investments. The two master themes are: (1) CONTROL/REGULATION OF EMOTIONS including subthemes: Challenges to unlocking emotion; Importance of therapeutic emotional containment; Role of Alcoholics Anonymous (AA) in the emotion sharing experience and (2) TRANSFORMATION/ALLEGIANCE TO SELF, including subthemes: Selfactualisation; Going into the heart of emotions as an emotional-spiritual journey. Participants expressed challenges to unlocking their emotions in therapy,which were mainly experienced as controlled or suppressed. Aging, masculinity and helpseeking theories, as well as addiction and recovery literature, are discussed in light of the findings along with suggestions for future research and implications in Counselling Psychology.

The influence of vitamin C on the pharmacokinetics of caffeine was investigated in ten elderly males, age 66 to 86 years. Caffeine (4 mg kg⁻¹) was administered intravenously on three different occasions over a seven-week period: before vitamin C restriction, after approximately four weeks of vitamin C restriction (15 mg dietary intake per day), and after two weeks of vitamin C supplementation (500 mg orally, twice daily). Blood and urine samples were collected over a 48-hour period following each caffeine administration. The plasma half-life (t₁/₂), rate constant of elimination (K), apparent volume of distribution (V), total body clearance (TBC), renal clearance (RC), and metabolic clearance (MC) of caffeine were determined. Simultaneous plasma (PVC), whole blood (WBVC), and leukocyte (WBCVC) vitamin C concentrations were obtained. All of the mean vitamin C values determined at the first kinetic trial (KT-1) were within the normal ranges for the respective biologic fluid or tissue. All of the mean vitamin C values changed significantly during the study; decreasing to below the normal ranges by the second kinetic trial (KT-2) following dietary vitamin C restriction, and increasing to the normal ranges by the third kinetic trial (KT-3) following vitamin C supplementation. All of the decreases and increases in the individual and average vitamin C concentrations paralleled the observed decreases and increases in the daily vitamin C intake. None of the caffeine pharmacokinetic parameters evaluated changed significantly during the study. The mean rate constant of elimination was approximately 0.15 hr⁻¹, the average plasma half-life was approximately 4.5 hours, and the mean apparent volume of distribution was approximately 500 ml kg⁻¹ for all three kinetic trials. The average total body, renal, and metabolic clearances were approximately 76.9, 1.3, and 76.0 (ml hr⁻¹)kg⁻¹, respectively, for all three kinetic trials. With the exception of V and TBC, the various pharmacokinetic characteristics investigated were in general agreement with data reported for younger subjects. The average apparent volume of distribution determined at any of the kinetic trials was about 16% lower than the value reported for young, healthy subjects. Similarly, the mean total body clearance observed was about 21% lower than that observed in young, healthy subjects. Since the average elimination rate constant observed in these elderly subjects is similar to the values observed in younger subjects and since TBC is equal to the product of V times K, the reduced TBC observed in this study appears to be due to the reduction in V, rather than to a decrease in the intrinsic metabolic capacity of the liver with aging. No relationship between vitamin C intake and/or body levels and the pharmacokinetics of caffeine was observed. These results indicate that the elimination of caffeine in the elderly is not affected significantly by the concentrations of vitamin C achieved during the study.

The purpose of this study was to examine the effects of androstenedione supplementation on testosterone levels in older men. Healthy men (n = 11) between the ages of58 and 69 were divided into two groups: 6 taking 300 mg of androstenedione (mean ± SE, 62.33 ± 2.57) supplement and 5 taking the 300 mg cellulose placebo (mean ± SE, 60.2 ± 1.02) for a period of seven days. Subjects in both groups had been participating in the Ball State University Adult Fitness Program (BSUAFP) for at least one year, incorporating both aerobic and resistance training into their workouts. Testing measures involved the subjects performing two exercises (leg extension and leg curl) while having blood drawn prior to, during, and post-exercise for a period of 20 minutes both pre-and post-supplementation. Specific weights for the subjects were determined with a ten-repetition maximum (10-RM) lift on both exercises. It appeared that the subjects in the androstenedione group were stronger with the exercises than the subjects in the placebo group, but with no significance. Testosterone, estradiol, and androstenedione were analyzed via hormone assay pre-and post-supplementation. The analysis of the testosterone revealed a significant difference pre-(mean ± SE, 4.65 ± .51 ng/ml) to post-(mean ± SE, 6.72 ± .58 ng/ml) supplementation for the androstenedione group. Analysis of the androstenedione revealed a significant difference pre-(mean ± SE, 0.88 ± .20) to post-(mean ± SE, 7.46 ± 1.25) supplementation for the androstenedione group. The estradiol assay revealed no significant differences pre-to post-supplementation for either group. The placebo group did not demonstrate any significant differences pre-to post-supplementation for either testosterone or androstenedione. The results of this study concluded that supplementation with 300 mg. of androstenedione for a period of seven days significantly elevated blood testosterone in older men. / School of Physical Education

This thesis focused on the development of a curriculum guide for a cancer awareness program for older men. The background of the problem -- a lack of programs for older men -- and the methods used in developing the guide are detailed in Chapter One. The second chapter consists of current information on disease prevention, aging and cancer with the emphasis on age-related changes and learning needs of older adult men. Chapter Three is the completed instructor's curriculum guide, and the final chapter includes recommendations on implementing the program as part of a community wellness program. The guide could also be used in senior centers, hospital educational programs, or adapted for use in staff inservices.

We examined the effect of daily stress, age, and emotional stability/neuroticism on stress reactivity, using cortisol diurnal rhythms. We used data from the Normative Aging Study (Spiro & Bosse, 2001). The 72 men in this study ranged from 67-93 (M =79.29, SD =4.88). Multilevel modeling showed that higher daily stress predicted flatter cortisol diurnal rhythms, B = .09, p < .001, as did age, B = .01, p < .001, while those higher in neuroticism on the emotional stability/neuroticism measure showed steeper slopes for cortisol diurnal rhythms, B = -.04, p < .001. These results indicate that age and emotional stability/neuroticism levels explain some of the variance in individual differences in stress reactivity and provide a basis for future research focused on the effects of psychosocial variables on physiological outcomes. / Graduation date: 2013
