  • does Mood State change risk taking tendency in older adults
    Psychology and Aging, 2007
    Co-Authors: Kee Lee Chou, Tatia M C Lee
    Abstract:

    No study has been conducted to evaluate the influences of age differences on specific Moods for risk taking tendencies. This study examined the patterns of risk taking tendencies among younger and older persons in 3 transient affective States: positive, neutral, and negative Moods. By means of viewing happy, neutral, or sad movie clips, participants were induced to the respective Mood. Risk taking tendencies were measured with decision tasks modified from the Choice Dilemmas Questionnaire (N. Kogan & M. A. Wallach, 1964). Consistent with the affect infusion model (J. P. Forgas, 1995), risk taking tendency was greater for those individuals who were in a happy Mood than for those who were in a sad Mood, for both young and older participants. However, an asymmetrical effect of positive and negative Mood on risk taking tendency was identified among both the young and older participants, but in opposite directions. These results are consistent with the predictions of the negativity bias and the positivity effect found in young and older adults, respectively, and are interpreted via information processing and motivation effects of Mood on the decision maker.

  • could Mood State affect risk taking decisions
    Journal of Affective Disorders, 2003
    Co-Authors: Kenneth S L Yuen, Tatia M C Lee
    Abstract:

    Abstract Background: Depressed patients are advised by clinicians to avoid making critical life decisions because their decision-making process might be influenced by their pathological Mood States. In order to provide empirical support for this practice, we examined the influence of different Mood States on risk-taking tendencies that govern one’s decision during critical life decisions. Method: By means of viewing a happy, neutral or sad movie clip, participants were induced to a respective Mood. Risk-taking tendencies were then measured with decision tasks modified from the Choice Dilemmas Questionnaire (Kogan N., Wallach, M.A., 1964. Risk Taking: A Study in Cognition and Personality, Holt, New York). Results: The findings (SS=54) indicated varying risk-taking tendencies in different Mood States: individuals in induced depress Mood were significantly more conservative in taking risk than those who were in neutral Mood, whilst people in induced elated Mood did not differ significantly from those in neutral Mood. Correlation between Mood-ratings with risk-taking tendency was positive (r=0.319, P

  • effects of multi ingredient preworkout supplements on physical performance cognitive performance Mood State and hormone concentrations in recreationally active men and women
    Journal of Strength and Conditioning Research, 2020
    Co-Authors: Meaghan E Beckner, Paul J Arciero, Alexis A Pihoker, Matthew E Darnell, Kim Beals, Mita Lovalekar, Felix Proessl, Shawn D Flanagan, Bradley C Nindl, Brian J Martin
    Abstract:

    Beckner, ME, Pihoker, AA, Darnell, ME, Beals, K, Lovalekar, M, Proessl, F, Flanagan, SD, Arciero, PJ, Nindl, BC, and Martin, BJ. Effects of multi-ingredient preworkout supplements on physical performance, cognitive performance, Mood State, and hormone concentrations in recreationally active men and women. J Strength Cond Res XX(X): 000-000, 2020-Performance enhancement supplement research has primarily focused on the effectiveness of individual ingredients, rather than the combination. This study investigated the acute effects of 2 multi-ingredient preworkout supplements (MIPS), with beta-alanine and caffeine (BAC) and without (NBAC), compared with placebo (PLA) on anaerobic performance, endurance capacity, Mood State, cognitive function, vascular function, and anabolic hormones. Thirty exercise-trained individuals (24.4 ± 4.9 years, 15 men and 15 women) completed a fatiguing exercise protocol on 3 separate occasions, 30 minutes after ingestion of BAC, NBAC, or PLA. Outcomes were analyzed using one-way or two-way repeated-measures analysis of variance, as appropriate (alpha = 0.05). Anaerobic power was greater when supplementing with NBAC (10.7 ± 1.2 W·kg) and BAC (10.8 ± 1.4 W·kg) compared with PLA (10.4 ± 1.2 W·kg) (p = 0.014 and p = 0.022, respectively). BAC improved V[Combining Dot Above]O2peak time to exhaustion (p = 0.006), accompanied by an increase in blood lactate accumulation (p < 0.001), compared with PLA. Both NBAC and BAC demonstrated improved brachial artery diameter after workout (p = 0.041 and p = 0.005, respectively), but PLA did not. L-arginine concentrations increased from baseline to postsupplement consumption of BAC (p = 0.017). Reaction time significantly decreased after exercise for all supplements. There was no effect of supplement on Mood States. Exercise-trained individuals looking to achieve modest improvements in power and endurance may benefit from consuming MIPS before exercise.

  • relationship of blood pressure heart rate and behavioral Mood State to norepinephrine kinetics in younger and older men following caffeine ingestion
    European Journal of Clinical Nutrition, 1998
    Co-Authors: Paul J Arciero, Andrew W Gardner, N L Benowitz, Eric T Poehlman
    Abstract:

    Objective: To examine age-related differences in blood pressure, heart rate, behavioral Mood State and norepinephrine kinetics after caffeine ingestion in younger and older men. Design: Placebo-controlled, double-blind study. Setting: General Clinical Research Center, University of Vermont. Subjects: 10 older (O) (65–80 y) and 10 younger (Y) (19–26 y) healthy men who were moderate consumers of caffeine (Y=126±30 mg/d; O=160±44 mg/d:NS; mean±s.e.m.). Intervention: All volunteers were characterized for fasting plasma glucose, insulin and caffeine levels, body composition, anthropometry, physical activity, and energy intake. Before and after placebo and caffeine ingestion (5 mg/kg fat-free mass) test days, the following variables were measured in all subjects: heart rate, blood pressure, Mood State, and norepinephrine concentrations (NEconc), appearance (NEapp) and clearance (NEcl). Main outcome measures: Systolic and diastolic blood pressure, heart rate, Mood State, and norepinephrine kinetic responses to placebo and caffeine ingestion. Results: Following caffeine ingestion, plasma caffeine levels were similar in Y and O men. Systolic (SBP) and diastolic (DBP) blood pressure increased significantly (P<0.01) from baseline by 9% (130±6 vs 142±6 mmHg) and 3% (75±3 vs 77±3 mmHg), respectively, in O men following caffeine ingestion, but remained unchanged in Y men. Self-reported feelings of tension (P<0.05) and anger (P=0.06) decreased in O men, while anger tended to increase in Y men (P<0.06) following caffeine ingestion. Heart rates in both groups were unaltered following caffeine ingestion. No differences were noted at baseline between O and Y men for NEconc, NEapp and NEcl. After caffeine ingestion, NEconc were significantly greater in O than Y men, whereas NEapp and NEcl rates did not differ from baseline in either group. Blood pressure and subjective Mood State effects of caffeine were not related to changes in norepinephrine kinetics. Conclusion: Age may play a role in augmenting blood pressure response and reducing subjective feelings of anger and tension following caffeine ingestion, suggesting that the elderly are more reactive to the pressor and less sensitive to the subjective effects of the drug. These effects do not appear to be mediated by changes in sympathetic nervous system activity.

  • prevalence of axis ii comorbidities in bipolar disorder relationship to Mood State
    Bipolar Disorders, 2018
    Co-Authors: Robert M Post, Lori L Altshuler, Trisha Suppes, Gabriele S Leverich, Susan L Mcelroy, R W Kupka, Willem A Nolen, Mark A Frye, Paul E Keck, Heinz Grunze
    Abstract:

    Objectives A high incidence of Axis II personality disorders is described in patients with bipolar disorder; however, their relationship to Mood State remains uncertain. Methods A total of 966 outpatients with bipolar disorder gave informed consent and filled out the Personality Disorder Questionnaire, 4th edition (PDQ4) and a questionnaire on demographics and course of illness prior to Bipolar Treatment Outcome Network entry at average age 41 years. Patients were rated at each visit for depression on the Inventory of Depressive Symptoms-Clinician version (IDS-C) and for mania on the Young Mania Rating Scale (YMRS). In a subgroup, the PDQ4 was retaken during periods of depression and euthymia. Results Patients met criteria for most personality disorders at a much higher rate when they took the PDQ4 while depressed compared to while euthymic, and scores were significantly related to the severity of depression (IDS) and of mania (YMRS) assessed within 2 weeks of taking the PDQ. Even when euthymic, more than quarter to half of the patients met criteria for a cluster A, B or C personality disorder. Conclusions A wide range of personality disorders occur in bipolar patients, but are highly dependent on filling out the form while depressed compared to while euthymic. How this relates to having a personality disorder assessed using a structured clinical interview remains to be tested. However, higher PDQ4 scores are related to an earlier age of onset of bipolar disorder and other factors portending a more difficult course of bipolar disorder, and the optimal treatment of these patients remains to be illuminated.

  • Mood State effects on amygdala volume in bipolar disorder
    Journal of Affective Disorders, 2012
    Co-Authors: Lara C Folandross, John O Brooks, Jim Mintz, George Bartzokis, Jennifer Townsend, Paul M Thompson, Lori L Altshuler
    Abstract:

    Background Prior structural neuroimaging studies of the amygdala in patients with bipolar disorder have reported higher or lower volumes, or no difference relative to healthy controls. These inconsistent findings may have resulted from combining subjects in different Mood States. The prefrontal cortex has recently been reported to have a lower volume in depressed versus euthymic bipolar patients. Here we examined whether similar Mood State-dependent volumetric differences are detectable in the amygdala.

  • baseline Mood State measures as predictors of antidepressant response to scopolamine
    Psychiatry Research-neuroimaging, 2012
    Co-Authors: Maura L Furey, Allison C Nugent, Andrew M Speer, David A Luckenbaugh, Elana M Hoffman, Erica Frankel, Wayne C Drevets, Carlos A Zarate
    Abstract:

    Identifying predictors of antidepressant response will facilitate the successful treatment of patients suffering from depression. Scopolamine produces robust antidepressant responses in unipolar and bipolar depression. Here we evaluate the potential for baseline self-ratings to predict treatment response to scopolamine. Fifty-one unipolar and bipolar patients participated in a double-blind, placebo-controlled crossover trial. Following a single-blind placebo session, participants randomly received P/S or S/P (P=3 placebo; S=3 scopolamine (4μg/kg) sessions). Mood-State self-ratings (Profile of Mood State (POMS) and Visual Analog Scales (VAS)) and depression severity (Montgomery-Asberg Depression Rating Scale (MADRS)) were obtained before each infusion. Day 1 (baseline/placebo) self-ratings were used in a discriminant function analysis to identify linear combinations of individual items that predict response. The discriminant analysis significantly separated responders from non-responders in both the unipolar and bipolar diagnostic subgroups. The discriminant functions accurately classified over 85% of patients as responders/non-responders. The POMS depression subscale significantly correlated with clinical response, as did the VAS restlessness, sad, and irritated scales. These results indicate that self-report Mood-ratings obtained before treatment can predict response outcome to scopolamine, and suggest that a constellation of Mood-State features may be related to clinical response.

Fifty-one unipolar and bipolar patients participated in a double-blind, placebo-controlled crossover trial. Following a single-blind placebo session, participants randomly received P/S or S/P (P=3 placebo; S=3 scopolamine (4ug/kg) sessions). Mood-State self-ratings (POMS and VAS) and depression severity (MADRS) were obtained before each infusion. Day 1 (baseline/placebo) self-ratings were used in a discriminant function analysis to identify linear combinations of individual items that predict response. The discriminant analysis separated responders from non-responders in both the unipolar (Chi-square=22.6, p=0.002) and bipolar (Chi-square=11.2, p=0.025) diagnostic subgroups. The discriminant functions accurately classified over 85% of patients as responders/non-responders. The POMS depression subscale correlated with clinical response (r=-.47; p<0.001), as did the VAS restlessness (r=-.49; p<0.001), sad (r=-.49, p<0.0001) and irritated (r=-.40, p=0.004) scales. These results indicate that self-report Mood-ratings obtained prior to treatment can predict response outcome to scopolamine, and suggest that a constellation of Mood-State features may be related to clinical response.
