Infant colic and maternal depression

The combined impact of infant colic and maternal depression on infant, parent, and family difficulties was examined. The sample included 93 consecutive patients seen at an outpatient Colic Clinic. Most mothers had private insurance and completed high school. Infants were approximately 2 months of age. Questionnaires completed by the mother prior to treatment onset were used to measure depressive symptoms in the mothers, infant cry, sleep and temperament, characteristics, parenting stress, maternal self‐esteem, social support, and family function. Moderate to severe depressive symptoms were reported by 45.2% of the mothers. More severe depressive symptoms in the mothers were related to fussy/difficult infant temperament, more parenting stress, lower parental self‐esteem, and more family‐functioning problems. Pediatric health care providers need to be aware that the combined effects of colic and maternal depression can be problematic for the family. ©2005 Michigan Association for Infant Mental Health.     

Fears in clinic-referred children: relations with child anxiety sensitivity, maternal overcontrol, and maternal phobic anxiety

Relations among maternal phobic anxiety, maternal overcontrol, child anxiety sensitivity, and child level of fear were explored in 156 children referred to an outpatient clinic for psychological evaluation. In addition, these relations were examined separately in analyses of age, gender, and diagnostic status. Overall, age, gender, and child anxiety sensitivity, along with maternal ratings of an overly controlling parenting strategy were significant predictors of levels of fear. These four variables predicted approximately 50% of the variance associated with fear levels. Surprisingly, maternal phobic anxiety was not a significant predictor in this sample of clinic-referred children. In separate analyses of age, gender, and diagnostic status (presence or absence of an anxiety disorder), anxiety sensitivity was a significant predictor of fear levels for both older and younger children, for both boys and girls, and for both children with and without an anxiety disorder. However, maternal overly controlling parenting strategy was significant only for the younger children (and not the older ones) and only for girls (and not boys). Moreover, maternal overcontrol was a marginally significant predictor for the anxiety-disorder group (and not the non-anxiety-disordered group). Results are discussed within a developmental framework, and implications for treatment are explored.     

Interactions between mothers and infants: impact of maternal anxiety

The aim of the study was to examine the impact of anxiety in the postnatal year on maternal contribution to mother-infant interaction. Participants were 32 mothers with high anxiety and 32 mothers with low anxiety, when their infants were aged 10-14 months. Mother-infant interaction was videotaped during a standardized play situation and coded blind to group status. High trait anxiety mothers showed less sensitive responsivity (p<.05) and reduced emotional tone (p<.05) during interaction. When participants scoring high in depressive symptomatology were removed for a subgroup analysis, the same pattern of results was obtained, suggesting that the observed differences in mother-infant interaction were due to group differences in anxiety.     

Isatin: role in stress and anxiety

(Indoledione 2,3) isatin is an endogenous indole found both in mammalian brain and peripheral tissues. Isatin concentration in blood can exceed 1 microM and tissue concentrations vary from < 0.1 to 10 microM. Its level in the brain and periphery is increased by stress. Isatin has a wide spectrum of behavioural and metabolic effects. It is anxiogenic at lower doses and sedative at higher doses. Its most potent known in vitro actions are as an antagonist of atrial natriuretic peptide (ANP) function and NO signaling. In this review, we discuss isatin and stress in animal models, the few human studies, and also what it is known to date about the molecular mechanisms of its action. We suggest the possibility that isatin and its analogues may be interesting new pharmacological agents; Isatin antagonists may be anxiolytic, and isatin agonists may activate the HPA axis.     

Generalised anxiety: A controlled treatment study

The effects of anxiety management training were evaluated by allocating 66 generally anxious clients to either a wait list condition, non-directive counselling, or a combination of relaxation and brief cognitive therapy. Anxiety management was significantly more effective than the wait list condition on a number of relevant measures at post-treatment, but there were relatively few differencs between anxiety management and non-directive counselling, either at post-treatment or at 6 months follow-up. Those differences which were found could plausibly be explained in terms of the demand characteristics of training in relaxation or cognitive therapy. It was concluded that anxiety management is clearly better than a non-treatment control condition, but that its superiority to plausible alternatives which lack the specific components thought to be responsible for improvement has yet to be demonstrated.     

Tracking stress,depression, and anxiety across the final year of secondary school: A longitudinal study

Levels of distress, which include stress, depression, and anxiety, are often heightened during the final year of secondary school and have been linked to major examinations that occur during this time period. However, relatively little is known about how these symptoms change over the course of the year or what moderates symptom severity. Using a longitudinal survey design, we tracked student outcomes and potential moderators (i.e., gender, test anxiety, self-efficacy, connectedness with peers, school and family, perceived use of fear appeals by teachers) associated with stress, depression, and anxiety once per term (i.e., 4 times total) over the final year of high school in seven Australian high schools. We hypothesised that student symptoms would increase over time and that symptom severity would be moderated by individual and environmental factors. Six hundred and thirty-eight unique students (M age = 16.95 years, SD = 0.56, range = 15–18 years, female = 474 [74.29%]) participated in at least one of the four surveys administered during each term of the final year of high school. Linear mixed models indicated that stress (d = 0.2) and anxiety (d = 1.7) increased over time. When all potential moderators of distress were entered into the full model, gender, test anxiety, emotional self-efficacy, and peer connectedness were all significant unique predictors of stress. Similar patterns were found for symptoms of depression and anxiety. Time 3 stress was predicted by unique variance in baseline stress, higher test anxiety, and academic self-efficacy. Overall distress increased over time and was moderated by gender, as well as by test anxiety, self-efficacy, and peer connectedness, which are areas that can then be targeted by interventions designed to maintain distress at optimum levels for wellbeing and academic performance.     

Prenatal maternal stress and prematurity: a prospective study of socioeconomically disadvantaged women.

Developed and tested a biopsychosocial model of birthweight and gestational age at delivery using structural equation modeling procedures. The model tested the effects of medical risk and prenatal stress on these indicators of prematurity after controlling for whether a woman had ever given birth (parity). Subjects were 130 women of low socioeconomic status interviewed throughout pregnancy in conjunction with prenatal care visits to a public clinic. The majority of women were Latino or African-American. Half were interviewed in Spanish. Lower birthweight was predicted by earlier delivery and by prenatal stress. Earlier delivery was predicted by medical risk and by prenatal stress. Parity was not related to time of delivery or to birthweight. Implications of results for the development of biopsychosocial research on pregnancy and on stress are discussed.     

Prenatal maternal anxiety and early childhood temperament

The consequences of exposure to prenatal maternal anxiety for the development of child temperament were examined in a sample of 120 healthy, 2-year-old children. Prenatal maternal state and pregnancy-specific anxiety (PSA) were measured five times during pregnancy, and maternal state anxiety was measured again at 2 years post partum. Child temperament was measured at 2 years using the Early Childhood Behavior Questionnaire. The relationship between the trajectory of maternal anxiety across gestation and negative affectivity was evaluated using hierarchical linear growth curve modeling. Higher maternal PSA between 13 and 17 weeks of gestation was associated with increased negative temperament in the children. This association could not be explained by postnatal maternal anxiety, demographic, or obstetric factors. Prenatal maternal state anxiety was not associated with child temperament. These findings demonstrate that PSA early in gestation has a distinctive influence on the developing fetus.     

Cumulative lifetime stress exposure,depression, anxiety,and well-being in elite athletes: A mixed-method study

Research suggests that elite athletes are at increased risk of poor mental health, partly due to the intense demands associated with top-level sport. Despite growing interest in the topic, the factors that influence the mental health and well-being of elite athletes remain unclear. From a theoretical perspective, the accumulation of stress and adversity experienced over the life course may be an important factor. To investigate this possibility, we employed a mixed-method design to: (a) examine whether cumulative lifetime stress predicted depression, anxiety, and well-being in elite athletes; and (b) help explain why cumulative lifetime stress exposure might have resulted in poor mental health and well-being. Ninety-five elite athletes (M_age = 29.81, SD = 10.88) completed the Stress and Adversity Inventory, Patient Health Questionnaire, Generalized Anxiety Disorder 7-item scale, and the Scales of General Well-Being. Hierarchical regression analyses revealed that total count and severity of lifetime stressor exposure significantly predicted greater depression (β = .42, p < .001; β = .46, p < .001) and anxiety symptoms (β = .34, p = .003; β = .28, p = .018), and worse well-being (β = -.42, p < .001; β = -.30, p = .015). Semi-structured interviews were then conducted with six athletes. Thematic analysis revealed that cumulative lifetime stress exposure fostered poor mental health and well-being by promoting maladaptive long-term coping strategies, increasing susceptibility to future stress, and limiting interpersonal relationships. We believe these findings can help practitioners identify, and intervene accordingly with, elite athletes at risk of experiencing stress-related mental health problems.     

Effects of natural stress relief meditation on trait anxiety: a pilot study

Natural Stress Relief meditation, a mental technique which is practiced for 15 minutes twice a day, aims to reduce stress and anxiety by eliciting a specific state of physiological rest along with mental alertness. The meditation is taught in a self-administered program, requiring one hour of training during the first three days, followed by the regular twice daily practice. Each 15-min. session consists in sitting quietly with closed eyes while applying a specific mental procedure. To test the effectiveness of meditation in reducing trait anxiety, Spielberger's State-Trait Anxiety Inventory was administered to 25 participants four times over a 3-wk. period: one week before starting to practice the meditation, a few hours before starting, 1 wk. after, and 2 wk. after. The difference in Trait Anxiety score between pretreatment and before starting the practice was not significant, while it was significant both after the first week of practice (Cohen d=.46) and after the first 2 wk. of practice (d=.67).     

Interactions between mothers and children: impacts of maternal and child anxiety

This study, an expansion of an earlier study of parenting behaviors of anxious mothers, examined the relationship of both mother and child anxiety disorders to mother behavior in parent--child interactions. Participants were 68 mother--child dyads with children ranging in age from 7 to 15 years. Mothers and children completed diagnostic evaluations and engaged in conversational tasks; behaviors were rated by coders who were blind to diagnosis. Mothers of anxious children, regardless of their own anxiety, were less warm (p <.05) toward their children. They also granted less autonomy (p <.01). There was an interaction between mother and child anxiety in predicting maternal catastrophizing (p <.01), with anxious mothers and nonanxious mothers of anxious children likely to catastrophize. Theoretical and research implications are discussed.     

Correlation between maternal stress and children's stress

Mothers (N = 168, M age = 37.0 yr., SD = 4.6) responded to a questionnaire of scales measuring sources of stress and symptoms of stress within themselves, and symptoms of stress in their 5-8-yr.-old children (61 girls, 98 boys; M age = 7.3 yr., SD = 1.0). Scores on all scales intercorrelated significantly, indicating a relationship between maternal stress and stress of the child. Both types of stress also correlated with the frequency of punishment of the child. Both maternal stress and frequency of punishment predicted stress symptoms in the children, maternal stress being a somewhat stronger predictor.     

Stepmothers and natural mothers: A study of maternal attitudes

The maternal attitudes of 15 natural mothers (M_d age 46) and 15 stepmothers (M_d age 47) were compared. The HerefordParent Attitude Survey was the instrument used to assess differences between the two populations on five scales measuring confidence, causation, acceptance, understanding, and trust. No significant differences were found between the two populations with the exception of the causation dimension (t=2.4840 p<.05), which indicated that stepmothers attribute the problem behavior of the child to genetic and environmental factors while natural mothers accept the influence of the maternal role in the child's problem behavior. It is the authors' opinion that the statistical similarities and differences found between the two samples is a reflection of the common problem they share, that of a child in treatment.     

The cortisol awakening response: Associations with trait anxiety and stress reactivity

This study investigated the extent to which trait anxiety and state anxiety in response to stress are associated with the cortisol awakening response (CAR).Fifty-one healthy participants were recruited. State anxiety measures were taken in anticipation of and during a laboratory stressor. Salivary cortisol levels were measured immediately upon awakening (at 0, 15, 30, and 45 min) on two consecutive mornings. Cortisol awakening response was assessed by the area under the curve with respect to zero (AUC_G).The magnitude of the CAR was found to be negatively associated with both trait anxiety and anticipatory anxiety. Moreover, regression analysis showed that the effects of trait anxiety on the AUC_G were mediated by anticipatory anxiety.These results suggest that the CAR is influenced by trait anxiety. Moreover, the effect of trait anxiety on the CAR seems to operate by impacting on psychological stress reactivity (i.e., anticipatory anxiety).
