Generativity and successful parenting: an analysis of young adult outcomes.

J Pers. 2006 Jun;74(3):847-69

Authors: Peterson BE

Generativity scores were assessed in parents and correlated with offspring outcomes. The offspring were participants in a longitudinal study spanning their first and senior years of college. Generativity of parents was positively related to offspring agreeableness and conscientiousness. Parental generativity was also related to offspring scores on future time orientation and positive affect. In addition, generative parents seemed to model their political interests to offspring, and that modeling was related to children's higher scores on generativity and greater interest in politics. Parental generativity was also related to offspring religiosity. Most of these relationships remained significant after controlling for offspring scores on generativity. Generativity of parents appears to be related to successful offspring outcomes.

Impaired allocentric spatial memory underlying topographical disorientation.

Rev Neurosci. 2006;17(1-2):239-51

Authors: Burgess N, Trinkler I, King J, Kennedy A, Cipolotti L

The cognitive processes supporting spatial navigation are considered in the context of a patient (CF) with possible very early Alzheimer's disease who presents with topographical disorientation. Her verbal memory and her recognition memory for unknown buildings, landmarks and outdoor scenes was intact, although she showed an impairment in face processing. By contrast, her navigational ability, quantitatively assessed within a small virtual reality (VR) town, was significantly impaired. Interestingly, she showed a selective impairment in a VR object-location memory test whenever her viewpoint was shifted between presentation and test, but not when tested from the same viewpoint. We suggest that a specific impairment in locating objects relative to the environment rather than relative to the perceived viewpoint (i.e. allocentric rather than egocentric spatial memory) underlies her topographical disorientation. We discuss the likely neural bases of this deficit in the light of related studies in humans and animals, focusing on the hippocampus and related areas. The specificity of our test indicates a new way of assessing topographical disorientation, with possible application to the assessment of progressive dementias such as Alzheimer's disease.

The boundary vector cell model of place cell firing and spatial memory.

Rev Neurosci. 2006;17(1-2):71-97

Authors: Barry C, Lever C, Hayman R, Hartley T, Burton S, O'Keefe J, Jeffery K, Burgess N

We review evidence for the boundary vector cell model of the environmental determinants of the firing of hippocampal place cells. Preliminary experimental results are presented concerning the effects of addition or removal of environmental boundaries on place cell firing and evidence that boundary vector cells may exist in the subiculum. We review and update computational simulations predicting the location of human search within a virtual environment of variable geometry, assuming that boundary vector cells provide one of the input representations of location used in mammalian spatial memory. Finally, we extend the model to include experience-dependent modification of connection strengths through a BCM-like learning rule - the size and sign of strength change is influenced by historic activity of the postsynaptic cell. Simulations are compared to experimental data on the firing of place cells under geometrical manipulations to their environment. The relationship between neurophysiological results in rats and spatial behaviour in humans is discussed.

Genetic testing and the relationship between specific and general self-efficacy.

Br J Health Psychol. 2006 May;11(Pt 2):221-33

Authors: Hendy J, Lyons E, Breakwell GM

The study examined the extent to which variations in health-specific self-efficacy could affect general self-efficacy. In a repeated measures design, 300 participants were administered an efficacy questionnaire, before and after an alleged news report, aimed at increasing or decreasing self-efficacy over genetic-testing decision making. The results found that self-efficacy over testing was significantly reduced after reading the negative news report in those participants who felt personal efficacy over testing decisions was important. Levels of general self-efficacy were also significantly decreased. The findings suggest that being denied control over a specific area of self-efficacy can have a wider impact, with a lack of perceived efficacy over testing decision making adversely impacting on levels of general well-being. The wider implications of this generalization effect and the processes involved in efficacy generalization are discussed.

Illness representations of coronary artery disease: an empirical examination of the Illness Perceptions Questionnaire (IPQ) in patients undergoing surgery, angioplasty and medication.

Br J Health Psychol. 2006 May;11(Pt 2):199-220

Authors: Hirani SP, Pugsley WB, Newman SP

BACKGROUND: This study sought to validate empirically, through factor analysis, the theoretically developed Illness Perceptions Questionnaire (IPQ) measure of illness representations, and investigated how illness representations varied within an illness condition between different treatments. METHODS: Two hundred and fourteen coronary artery disease (CAD) patients, 70 of whom were undergoing medication, 71 to undergo angioplasty and 73 to undergo coronary artery bypass surgery (CABG), completed the New Zealand Heart Attack Recovery Project version of the IPQ. The core cognitive illness representation statement responses were subject to principal components analyses (PCA), with oblique rotation. Identity data were examined regarding symptom frequency. Subscales based on factor structures and frequency scores were utilized to investigate treatment group differences in illness beliefs through analysis of covariance (ANCOVA). FINDINGS: PCA of the core components indicated four factors labelled: 'illness impact', 'duration', 'control', and 'self-image', accounting for 46.5% of the variance. The most frequently experienced symptoms were fatigue, breathlessness and chest-pain (angina). ANCOVAs showed significant treatment group differences in frequency of chest-pain experienced (medication<CABG, p<.01) and differences on illness 'duration' beliefs (medication>revascularization groups, p<.001). DISCUSSION: The results produced a modified structure for the IPQ, which appeared to reflect the nature of the illness under study and the possible fractionation of the core illness representation components. Responses on the subscales created were also related to the position within the 'subjective experience with the illness' that a patient had reached and the treatment being undertaken.

Emotions and respiratory function in asthma: a comparison of findings in everyday life and laboratory.

Br J Health Psychol. 2006 May;11(Pt 2):185-98

Authors: von Leupoldt A, Ehnes F, Dahme B

OBJECTIVES: The present study examined the influence of emotions on the respiratory function in asthmatic and non-asthmatic individuals in everyday life and the relationship to emotion-induced respiratory changes in the laboratory. METHODS: Affective states were induced in 10 asthmatic and 10 non-asthmatic participants by viewing affective picture series of either a pleasant, neutral, or unpleasant valence, while airway resistance (Raw) was measured with whole body plethysmography. Following this, individuals measured their mood, forced expiratory volume in the first second (FEV1), peak expiratory flow (PEF), physical activity, and medication use for 21 days with an electronic diary, which included a respiratory self-measurement device. Strong pleasant and unpleasant mood episodes were extracted from the diaries and compared with neutral affective states. RESULTS: Asthmatic patients showed increases of Raw after unpleasant and pleasant emotional stimulation in the laboratory, which was only found after a pleasant stimulation in non-asthmatic participants. In everyday life, no group differences were obtained. Episodes of strong unpleasant mood states were associated with decreases in PEF, whereas in contrast to the laboratory assessment, pleasant mood was associated with increases in PEF. Results for FEV1 were comparable, but non-significant. Physical activity and medication use did not vary systematically between affective episodes. PEF showed no significant relationship with Raw. CONCLUSIONS: Unpleasant mood is associated with decreased respiratory function in asthmatic patients in everyday life and in laboratory assessments, whereas effects of pleasant mood states are inconsistent. Pulmonary responses to laboratory-induced emotional conditions are not predictive of airways reactivity during daily life.

Hopelessness at the end of life: the utility of the hopelessness scale with terminally ill cancer patients.

Br J Health Psychol. 2006 May;11(Pt 2):173-83

Authors: Abbey JG, Rosenfeld B, Pessin H, Breitbart W

OBJECTIVES: We sought to investigate the utility of the Beck Hopelessness Scale (HS) in a sample of terminally ill cancer patients by examining the scale properties. Moreover, we sought to identify and remove potentially problematic items in order to ascertain a "purer" index of hopelessness for this population. DESIGN: A cross-sectional study of 200 hospice inpatients with a life expectancy of less than 6 months. The HS, as well as several other distress measures, were administered to patients at bedside by trained clinicians. METHODS: An item analysis of the HS was conducted, looking specifically at item endorsement and item-total correlations. Three abbreviated versions (3-item 7-item, 13-item) were developed based on certain denoted item-total correlation cut-offs. Reliability and validity of the original 20-item HS was then compared to that of the newly developed abbreviated version. RESULTS: All scales were found to be reliable and valid measures of hopelessness. The three abbreviated versions were more highly correlated with the distress measures than the original version, and the 7-item and 13-item subscales outperformed the original HS in the prediction of suicidal ideation and desire for hastened death. CONCLUSION: The data suggest that the HS may be improved, when applied to a terminally ill sample, by the elimination of problematic items. The development of a shorter, purer measure of hopelessness for this population is crucial given the need to reduce the burden placed on those who participate in end-of-life studies, and the important role of hopelessness in the prediction of suicide and desire for hastened death.

Development of a measure of the concerns held by people with implanted cardioverter defibrillators: the ICDC.

Br J Health Psychol. 2006 May;11(Pt 2):293-301

Authors: Frizelle DJ, Lewin B, Kaye G, Moniz-Cook ED

OBJECTIVES: To develop a questionnaire to measure the extent and severity of the concerns of people with an implanted cardioverter defibrillator. DESIGN: Items were generated from patient interviews, expert review and the research literature on patients' worries and concerns. A pilot version was administered to a series of ICD patients and repeated for test-retest reliability 6 weeks later. Psychometric tests including the screen test, factor analysis and various reliability assessments were undertaken. It was predicted that the greater the extent and severity of concerns, the greater the anxiety experienced by the ICD patient. Scores were compared with a validated measure of anxiety and depression administered at the same time. RESULTS: Fifty-seven (64%) patients completed and returned the questionnaire and a further 22 (100% of those asked) completed the 6-week retest. Reliability and validity appeared to be good and two factors were identified. Both total score and the individual factor scores correlated moderately with anxiety. CONCLUSIONS: The questionnaire appears to reflect patients' concerns and, as predicted, these were associated with the patients' anxiety level. The scale requires further testing to reveal if it is of use both clinically and for research purposes.

Social and emotional characteristics of adults seeking a cochlear implant and their spouses.

Br J Health Psychol. 2006 May;11(Pt 2):279-92

Authors: Knutson JF, Johnson A, Murray KT

OBJECTIVES: Because past research has shown that benefits of cochlear implantation may include a significant decrease in psychological and emotional difficulties, this study examined whether persons seeking cochlear implants in recent years differed psychologically from those referred in the early 1980s. A second objective was to explore mechanisms by which profound deafness could contribute to psychological and emotional difficulties for implant candidates and their spouses. METHODS: 178 cochlear implant candidates referred from 1981 to 1998 at the University of Iowa Hospitals completed a standard battery of psychological tests and questionnaires. The sample was divided into six 3-year cohorts and compared on standardized measures of psychological and emotional adjustment, and in participation in social and non-social activities. Spouses of implant candidates completed a similar assessment. RESULTS: The sample was characterized by elevations in depression, social introversion, suspiciousness, and social anxiety and loneliness. There were no significant differences among cohorts across time except for an increase in expectations for implant success. Spouses also evidenced elevated levels of psychological distress. Hearing status was associated with significant differences in social activity participation. A paradoxical interaction was found between marital status and deafness. CONCLUSIONS: There was no evidence that the psychological status of implant candidates is changing across time, suggesting continued psychological benefit for persons receiving cochlear implants. Both candidates and their spouses participated in fewer social activities than normal controls. Findings underscore the complex relation between marital status, deafness, and engagement and participation in positive activities.

A randomized controlled trial of smoking cessation for pregnant women to test the effect of a transtheoretical model-based intervention on movement in stage and interaction with baseline stage.

Br J Health Psychol. 2006 May;11(Pt 2):263-78

Authors: Aveyard P, Lawrence T, Cheng KK, Griffin C, Croghan E, Johnson C

OBJECTIVES: To examine whether, as predicted by the transtheoretical model (TTM), stage-matched interventions will be more effective than stage-mismatched interventions. DESIGN: Randomized controlled trial of smoking cessation advice to pregnant smokers. METHODS: Pregnant women currently smoking at 12 weeks gestation were enrolled in a pragmatic three-arm trial of TTM-based interventions to help them stop smoking. One arm constituted standard midwifery advice and a self-help leaflet on stopping smoking, which is generally appropriate for women in preparation. Two arms were TTM-based. Differences in positive movement in stage towards quitting from enrolment to 30 weeks gestation and 10 days post-partum were calculated for each arm of the trial. We then examined whether, as predicted from the TTM, the relative benefit of the TTM-based intervention was greater for women in precontemplation and contemplation, for whom the control intervention was stage-mismatched, than for women in preparation, for whom the control intervention was stage-matched. RESULTS: Women in the TTM-based arms were statistically significantly more likely to move forward in stage than were women in the control arm. Contrary to the TTM-derived hypothesis, the greater relative benefit of the TTM-based intervention was seen for women in preparation stage at baseline, rather than women in precontemplation and contemplation. CONCLUSIONS: The TTM-based intervention was more effective in stage movement, but this could be due to its greater intensity. The failure to confirm that stage-matching was important casts doubt on the validity of the TTM in explaining smoking cessation behaviour in pregnancy.

Using past behaviour and spontaneous implementation intentions to enhance the utility of the theory of planned behaviour in predicting exercise.

Br J Health Psychol. 2006 May;11(Pt 2):249-62

Authors: Brickell TA, Chatzisarantis NL, Pretty GM

OBJECTIVES: This study examined the utility of the theory of planned behaviour (TPB), past behaviour, and spontaneous implementation intentions in predicting exercise behaviour. The psychological correlates of spontaneous implementation intentions and the moderating effects of intention, perceived behavioural control, past behaviour, and implementation intentions at various time points were also examined. DESIGN: Data collection occurred over three phases with a 2- and 3-week interval. The attrition rate was 35.97% leaving a total of 162 participants (63 males, 99 females). In the first wave, participants completed measures of TPB, spontaneous implementation intentions, and past behaviour. Behaviour was assessed in the second and third waves, and a follow-up measure of spontaneous implementation intentions was completed in Phase 3. RESULTS: Several regression analyses were conducted. Attitude towards exercise and perceived behavioural control made a significant contribution to the prediction of intention. Intention made a significant contribution to the prediction of implementation intentions. Spontaneous implementation intentions reduced the effect of intention and past behaviour for behaviour at 2 weeks and when indexed over a 5-week period. When behaviour was measured for a 3-week period (following an initial 2-week period), the variance that intention and past behaviour accounted for in exercise behaviour decreased, and spontaneous implementation intentions were no longer a significant predictor of behaviour. Spontaneous implementation intentions were found to interact with past behaviour, such that implementation intentions predicted exercise behaviour only among participants who did not exercise frequently in the past. CONCLUSIONS: Implications and future research directions are discussed.

Examination of a sociocultural model of disordered eating among male and female adolescents.

Br J Health Psychol. 2006 May;11(Pt 2):235-48

Authors: Halliwell E, Harvey M

OBJECTIVES: The study tests a version of Stice's (1994) sociocultural model of disordered eating that was modified to incorporate social comparisons. Additionally, it examines how self-reported body-mass index and perceived weight status influence associations within the model. METHOD: Questionnaires were administered in a state secondary school; the sample consisted of 250 female and 257 male adolescents aged 11-16 years. RESULTS: The results supported the sociocultural model among both male and female adolescents. Perceived pressure to lose weight was directly associated with eating behaviour, as well as indirectly associated through social comparisons, internalization and body dissatisfaction. However, social comparisons were most strongly related to body dissatisfaction among adolescents who perceived themselves as overweight. CONCLUSIONS: The findings indicate that models of eating disordered behaviour, developed for adolescent girls, are also appropriate for understanding this behaviour among male adolescents. The results suggest that social comparisons represent a useful addition to Stice's (1994) original model and a potentially fruitful target for interventions.

A multi-level decomposition of variance in somatic symptom reporting in families with adolescent children.

Br J Health Psychol. 2006 May;11(Pt 2):345-55

Authors: Michel G

OBJECTIVES: This paper examines four different levels of possible variation in symptom reporting: occasion, day, person and family. DESIGN: In order to rule out effects of retrospection, concurrent symptom reporting was assessed prospectively using a computer-assisted self-report method. METHODS: A decomposition of variance in symptom reporting was conducted using diary data from families with adolescent children. We used palmtop computers to assess concurrent somatic complaints from parents and children six times a day for seven consecutive days. In two separate studies, 314 and 254 participants from 96 and 77 families, respectively, participated. A generalized multilevel linear models approach was used to analyze the data. Symptom reports were modelled using a logistic response function, and random effects were allowed at the family, person and day level, with extra-binomial variation allowed for on the occasion level. RESULTS: Substantial variability was observed at the person, day and occasion level but not at the family level. CONCLUSIONS: To explain symptom reporting in normally healthy individuals, situational as well as person characteristics should be taken into account. Family characteristics, however, would not help to clarify symptom reporting in all family members.

Does changing the order of threat and efficacy information influence the persuasiveness of threat messages?

Br J Health Psychol. 2006 May;11(Pt 2):333-43

Authors: Hall S, Bishop AJ, Marteau TM

OBJECTIVES: The aim of this study is to investigate the impact of changing the conventional threat-before-efficacy order of threat messages on the persuasiveness of a leaflet informing women smokers of the link between smoking and cervical cancer. DESIGN: The study used a between-groups design in which women smokers were sequentially allocated to one of three groups. Two groups received one of two leaflets aimed at providing information about the link between smoking and cervical cancer: one provided threat-before-efficacy information; the other provided efficacy-before-threat information. The third group received no leaflet. METHODS: Participants (N=178) were recruited by a commercial survey organization. Purposeful sampling was used to ensure that women with a wide range of ages and educational qualifications were included. Outcomes were intention to stop smoking, recall of information, and threat and efficacy perceptions. RESULTS: Although women in the 'efficacy-before-threat' group recalled more efficacy information, and those in the 'threat-before-efficacy' group recalled more threat information, the leaflets were similarly persuasive. Compared with women not given a leaflet, those given either of the two leaflets had greater intentions to stop smoking and higher threat and efficacy perceptions. CONCLUSIONS: Informing women of the link between smoking and cervical cancer increases their intentions to stop smoking. Changing the order of threat and efficacy information does not influence the persuasiveness of this message. Order effects may be more likely in experimental contexts using weaker messages or those that are not novel.

A systematic review of motivational interviewing in physical health care settings.

Br J Health Psychol. 2006 May;11(Pt 2):319-32

Authors: Knight KM, McGowan L, Dickens C, Bundy C

PURPOSE: Motivational interviewing (MI), a method of augmenting an individual's motivation to change problematic behaviours, is a patient-centred counselling style that seeks to help patients resolve ambivalence about behaviour change. MI has successfully been used in the field of addictions and has recently received increased interest as a means of promoting treatment adherence in physical health care settings. This systematic review is aimed to evaluate the effectiveness of MI interventions in physical health care settings. METHODS: Electronic databases were searched for articles specifying the use of 'motivational interviewing' in physical health care settings between 1966 and April 2004. Fifty-one relevant abstracts were yielded and data was extracted from eight relevant selected studies. RESULTS: Eight studies were identified in the fields of diabetes, asthma, hypertension, hyperlipidaemia, and heart disease. The majority of studies found positive results for effects of MI on psychological, physiological, and life-style change outcomes. Problems with research in this area include: small sample sizes, lack of power, use of disparate multiple outcomes, inadequate validation of questionnaires, poorly-defined therapy and training. CONCLUSIONS: While MI has high face validity across a number of domains in physical health care settings, the general quality of trials in this area is inadequate and therefore recommendations for its dissemination in this area cannot yet be made. More research into MI applied to health behaviour change is urgently required.
