Mindful Kangaroo Care: mindfulness intervention for mothers during skin-to-skin care: a randomized control pilot study.

BACKGROUND: Parents of babies admitted to the Newborn Intensive Care Unit (NICU) undergo considerable stress. There is evidence that mindfulness reduces stress in these parents. Kangaroo Care (KC) is practiced in NICUs across the world and is stress-relieving. Whether mindfulness practiced during KC in the NICU reduces parental distress has not yet been studied. The objective was to explore the feasibility and acceptability of teaching and practicing mindfulness during KC for mothers of premature babies. The objective was also to document preliminary outcomes of Mindful Kangaroo Care (MKC) on maternal stress, anxiety, depression, and mindful awareness. METHODS: In this pilot randomized controlled study, mothers of premature babies who were expected to stay in the NICU for at least four weeks were taught two mindfulness exercises to practice during KC and compared to mothers who received standard care with no mindfulness teaching. Mothers filled out stress, anxiety, depression and mindful awareness scales at recruitment and after four weeks. Acceptability and feasibility questionnaires were also completed. RESULTS: Fifteen mothers per group completed the study. The MKC group demonstrated a significant within-group reduction in anxiety (p = 0.003), depression (p = 0.02) and stress (p = 0.002), and a significant increase in both the curiosity (p = 0.008) and decentering (p = 0.01) scores of the Toronto Mindfulness Scale, all of which had medium to large effect sizes. Only the increases in curiosity and decentering were significant between groups. Fourteen mothers found the intervention acceptable, one neutral. CONCLUSION: MKC was acceptable, feasible and led to a reduction in stress, anxiety and depression in mothers who practiced mindfulness exercises during KC.

COMPULSIVE BUYING TENDENCIES.

Compulsive buying behavior is typically viewed as pathological, but recent research has shown that compulsive buying tendencies are associated with attitudes toward money, personal financial behavior, and having materialistic values, suggesting that compulsive buyers are manifesting an extreme form of habits shown by people in general. In a study of 240 community residents, scores on the Compulsive Buying Scale were associated positively with scores on the Material Values Scale and the Canadian Problem Gambling Index, and negatively with scores on the Executive Personal Finance Scale and Ardelt's wisdom scale. These results suggest that, as is the case for many abnormal behaviors, tendencies toward compulsive buying may not be pathological, but are associated with attitudes toward money in general, financial management behavior, and materialistic values.

Compulsive buying tendencies and personal finances.

In a community sample of 225 adults, scores on the Compulsive Buying Scale were associated with scores on the subscales of the Executive Personal Finance Scale (rs = -.35 to -.70) and the Money Attitudes Scale (positively with using money for impressing others, and negatively with saving and planning). The results suggested that common tendencies toward compulsive buying may not be pathological, but merely associated with attitudes toward money in general and financial management habits.

Personality correlates of financial behavior.

In a sample of 98 students, scores for extraversion, neuroticism, psychoticism, and a Lie scale were associated with financial behavior, with Lie subscale scores providing the majority of the significant but weak associations.

Gambling and delaying rewards as a function of current mood.

In a sample of 92 undergraduates, current mood was not associated with choosing to accept a delayed but larger reward or with gambling for a larger reward.

Correlations among executive function scales and positive psychological attributes in college students.

Scores on executive function scales were correlated with scores on attributes of positive psychology. Values were positive among gratitude, satisfaction, and the executive function scales of motivational drive, empathy, and strategic planning. If replicated and extended, such data may predict academic success in college students as in 13- to 14-yr.-olds.

Executive functions in morality, religion, and paranormal beliefs.

Moral, religious, and paranormal beliefs share some degree of overlap and play important roles in guiding peoples' behavior. Although partly cultural phenomena, they also have neurobiological components based on functional neuroimaging studies and research in clinical populations. Because all three show relationships to prefrontal system functioning, the current study examined whether they related to executive functions as measured by the Executive Function Inventory in a community sample. As in previous research, religious beliefs related positively to both moral attitudes and paranormal beliefs. Moral attitudes, however, did not relate to paranormal beliefs. Paranormal beliefs related inversely to impulse control and organization, whereas small positive correlations occurred between traditional religious beliefs, impulse control, and empathy. Moral attitudes, on the other hand, showed consistent positive correlations with all executive functions measured, independent of demographic influences. These findings concordantly support that prefrontal systems play a role in morality, religion, and paranormal beliefs.

Development of the Executive Personal Finance Scale.

There is accumulating evidence that prefrontal systems play an important role in management of personal finances, based on studies using clinical populations, functional neuroimaging, and both subjective and objective neuropsychological measures. This study developed the Executive Personal Finance Scale (EPFS) as a specific self-rating measure of executive aspects of personal money management. The resulting 20-item scale had good reliability and showed four factors: impulse control, organization, planning, and motivational drive. Validity was evidenced by correlations with income, credit card debt, and investments. The EPFS also showed logical correlations with compulsive buying and money attitudes. Second-order factor analysis of the EPFS and other scales revealed two higher-order factors of personal finance: cognitive (e.g., planning, organizing) and emotional (e.g., anxiety, impulse-spending, prestige). The EPFS shows good psychometric properties, is easy to use, and will make a convenient complement to other research methodologies exploring the neural basis of personal finance management.

Normative data and a short form of the Barratt Impulsiveness Scale.

The Barratt Impulsiveness Scale is one of the most commonly used scales to measure impulsivity. It has demonstrated validity in several neuropsychiatric populations and correlates with objective neuropsychological measures and impulsivity-related behaviors in healthy individuals. Neuroimaging studies show that BIS scores relate to prefrontal structure and function, as well as central serotonergic function. This study reports normative data and demographic influences in a community sample (n = 700). A 15-item short form of the BIS (BIS 15) is presented that retains the 3-factor structure (nonplanning, motor impulsivity, and attention impulsivity), and maintained good reliability and validity.

The role of prefrontal systems in sexual behavior.

Research from a variety of methodologies is demonstrating a role for neuroanatomical structures in different aspects of sexual behavior. This article reviews the particular contribution of prefrontal-subcortical systems to sexual behavior, including regions of prefrontal cortex (i.e., dorsolateral, medial, and orbitofrontal cortex), and associated subcortical structures (i.e., basal ganglia and thalamus). Findings are integrated from functional neuroimaging and clinical studies in humans, as well as animal studies, which convergently illustrate the role of different prefrontal systems. In addition to providing a clearer understanding of normal sexual behavior, appreciation of prefrontal systems in sexual behavior has implications for disorders of sexual behavior. Consistent with their role in other forms of cognition, emotion, and behavior, prefrontal systems serve in an executive capacity to regulate sexual behavior.

Measuring the executive regulation of emotion with self-rating scales in a nonclinical population.

Prefrontal systems play an important role in the regulation of emotion as evidenced by clinical neuroimaging studies. Both subjective and objective neuropsychological tests provide functional evidence of executive dysfunction in emotional deregulation. The present authors evaluated these relationships here in a nonclinical community sample using the Frontal Systems Behavior Scale, Profile of Mood States (POMS), and Depression Anxiety Stress Scales (DASS). Positive correlations uniformly emerged between prefrontal system dysfunction and negative emotional states (anger, depression, anxiety, stress, confusion, and fatigue), whereas positive emotion (vigor) showed a modest inverse correlation with prefrontal system dysfunction, even after control for demographic influences. These relationships may result from cognitive strategies for managing emotion mediated by reciprocal connections between prefrontal systems and the limbic system. The findings corroborated those of other methodologies, supporting the Frontal Systems Behavior Scale (FrSBe) as a valid tool to measure prefrontal function in nonclinical populations.

The executive personal finance scale: item analyses.

A scale devised to measure executive personal money management was examined for its factorial structure using 138 college students. On the whole, the factor analysis confirmed the subscale structure of the scale, but the Planning subscale appeared to consist of two distinct components, investment behavior and saving behavior.

Correlations among measures of executive function and positive psychological attributes in college students.

Executive functions are cognitive abilities that allow for more goal-oriented and autonomous behavior. The authors examined the relationship between self-rated executive functions and 3 positive personality attributes (satisfaction with life, gratitude, and forgiveness) in a nonclinical community sample. The authors used self-report scales (Executive Function Index, Heartland Forgiveness Scale "other" subscale, Satisfaction With Life Scale, and the Gratitude Questionnaire) to examine how executive functions related to the positive psychology attributes. After controlling for age, sex, and formal education, positive relationships emerged among gratitude, satisfaction, and executive function scales of motivational drive, empathy, and strategic planning. However, an inverse relationship emerged between impulse control and forgiveness, perhaps relating to cautiousness and suggesting finer distinctions between adaptive and maladaptive forms of forgiveness. These findings suggest common psychological and neurobiological substrates for executive functions and positive psychology attributes, warranting further, more direct biobehavioral research.

Neurotransmitter-related personality traits and money attitudes: a study in neuroeconomics.

In a sample of 82 undergraduates, the personality dimension of novelty seeking, which has been hypothesized to be influenced by levels of dopamine in the central nervous system, was associated with attitudes regarding money.

Prefrontal cortex dysfunction and income: a study in neuroeconomics.

In four samples of adults, individual income was negatively associated with a measure of prefrontal cortex dysfunction even after implementing controls for age, sex, and education. The small association was stronger for men than for women. These results provide support for a neuroeconomic approach to the study of micro-economic variables.

Depression, anxiety, and personal finance behavior: implications for the classical economic conception of humans as rational decision-makers.

In a sample of 138 college students, the personal finance behaviors of impulse control and organization were negatively associated with the use of recreational drugs and with scores on measures of depression, mania, and anxiety.

Can money buy happiness?

Income was negatively associated with the mood states of confusion and tense in a sample of 406 community residents, but controls for age, sex, and education eliminated these associations.

A paper-and-pencil measure of prefrontal subcortical dysfunction.

In a large sample of 722 community residents, scores on the Frontal Systems Behavior Scale were significantly associated with age, sex, and education, indicating that scores were higher for men, younger participants, and less educated participants.

Predicting credit card behavior: a study in neuroeconomics.

In a sample of 139 community residents, credit card ownership was associated with age, sex, income, attitudes toward credit cards and toward money, and scores on a verbal measure of prefrontal cortical dysfunction, supporting a neuroeconomic approach to economic decision-making.

Prefrontal substrates of empathy: psychometric evidence in a community sample.

Empathy is a vicarious experience of others' emotions, and is crucial to many forms of adaptive social interaction. Clinical, experimental, and functional neuroimaging studies convergently suggest a role for prefrontal-limbic circuits in mediating empathy. This study examined the prefrontal basis of empathy in a community sample using self-report measures: the frontal systems behavior scale (FrSBe), Barratt impulsiveness scale (BIS), and the interpersonal reactivity index (IRI). Multiple correlations emerged supporting an inverse relationship between prefrontal system dysfunction and empathy, particularly emotional empathy and perspective taking. Many of these relationships persisted after controlling for age, sex, and education. However, FrSBe scales did not correlate with one's identification with fictional characters, and motor impulsivity correlated positively, presumably due to the different cognitive and emotional context (i.e. real versus fictional individuals). These studies parallel others using objective methodologies and suggest a graded relationship between prefrontal function and empathy and likely reflect normal variations in prefrontal-limbic function.
