Parental smoking and children's attention to smoking cues

The relation between parental chronic pain, pain-related attention and interpretation biases in pain-free adolescents

BACKGROUND

Children of chronic pain patients run greater risk for developing chronic pain themselves. Exposure to chronic pain of the parent might install cognitive (e.g., pain catastrophizing, interpretation and attentional bias) and affective (e.g., pain anxiety) vulnerability which increase the risk for the development of chronic pain complaints in offspring. This study examines whether pain-free offspring of parents with chronic pain complaints make more health-threatening interpretations and display a stronger pain-related attentional bias compared to the offspring of pain-free parents. We furthermore examined differences between both groups on pain catastrophizing, pain anxiety and somatic symptoms and explored the relations between parental pain catastrophizing and aforementioned pain vulnerability measures in offspring.

METHODS

Offspring of parents with chronic pain complaints (n = 24) and pain-free parents (n = 27) completed measures of attentional bias (i.e., pictorial dot probe), interpretation bias (i.e., ambiguous word association task), pain catastrophizing, pain anxiety and somatic symptoms. Parents completed measures of pain catastrophizing and psychological distress.

RESULTS

No differences between offspring of parents with and without pain complaints were observed on pain catastrophizing, pain anxiety and somatic symptoms. Both groups of healthy adolescents predominantly showed benign, non-health-threatening interpretations. Children of pain-free parents showed an attention bias for pain stimuli, while offspring of parents with pain complaints showed no such bias.

CONCLUSIONS

Future research is needed to further elucidate the precise role of parental pain in the development of pain-related biases and the significance of these biases in the onset and/or maintenance of a chronic pain condition in children and adolescents.

SIGNIFICANCE

Parental chronic pain may install psychological vulnerability for developing chronic pain and associated complaints in offspring. This study did not show differences in pain-directed attentional and interpretation bias between offspring of parents with chronic pain complaints and offspring of pain-free parents. Further (longitudinal) research is needed to elucidate the precise role of parental pain factors in the development of pain-related vulnerability in offspring of chronic pain parents, thereby identifying important targets for the prevention and early intervention of chronic pain.

The effect of parental smoking on preadolescents' implicit and explicit perceptions of smoking-related cues

Children of smokers are significantly more likely to experiment with cigarettes and become habitual smokers than children of nonsmokers. The current study examined the effect of parental smoking on children's implicit and explicit responses toward smoking behavior and smoking-related cues with the goal of identifying potential mechanisms for this relationship. A sample of 8-12-year-old children of smokers (n = 57) and children of nonsmokers (n = 86) completed a dot probe task to assess implicit attentional bias toward smoking cues and the Affect Misattribution Procedure (AMP) to assess implicit affective responses to smoking cues. In addition, children indicated their explicit perceptions of smokers and smoking behavior. Results demonstrated that children of smokers showed more sustained implicit attentional bias toward pictures of smoking stimuli presented alone than children of nonsmokers. Overall, participants showed negative implicit affective responses to smoking stimuli regardless of parental smoking. Children of smokers indicated that smokers would experience fewer negative consequences than children of nonsmokers; these relationships were moderated by age. Together, our findings suggest that parental smoking affects the ways that preadolescent children implicitly process smoking cues and their perceptions about smoking and its consequences. These findings help us understand the environmental mechanisms associated with smoking behavior in this vulnerable population. (PsycINFO Database Record (c) 2018 APA, all rights reserved).

Cognitive manifestations of drinking-smoking associations: preliminary findings with a cross-primed Stroop task

BACKGROUND

Despite tremendous growth in research examining the role of cognitive bias in addictive behaviors, scant consideration has been paid to the close association between smoking and drinking behavior. This study sought to determine whether an association between smoking and drinking could be observed at an implicit level using a novel cognitive bias task, as well as characterize the relationship between performance on this task and clinically relevant variables (i.e., heaviness of use/dependence).

METHODS

Individuals (N=51) with a range of smoking and drinking patterns completed a modified Stroop task in which participants identified the color of drinking, smoking and neutral words that were each preceded by drinking, smoking or neutral picture primes. Participants also provided information regarding the heaviness of their smoking and drinking behavior and completed self-report measures of alcohol and nicotine dependence.

RESULTS

Response times to smoking and drinking words were significantly slowed following the presentation of either smoking or drinking picture primes. This effect did not differ across subgroups. However, the strength of the coupling between smoking and drinking prime effects was greater among heavier drinkers, who also exhibited a concordant looser coupling of the effects of smoking and drinking primes on smoking words.

CONCLUSIONS

Associations between smoking and drinking can be observed at an implicit level and may be strongest for heavier drinkers.

Promoting smoking cessation among parents: effects on smoking-related cognitions and smoking initiation in children

BACKGROUND

Parental smoking is associated with an increased risk of smoking among youth. Epidemiological research has shown that parental smoking cessation can attenuate this risk. This study examined whether telephone counselling for parents and subsequent parental smoking cessation affect smoking-related cognitions and smoking initiation among children of smoking parents.

METHODS

Data of a two-arm randomized controlled trial were used in which 512 smoking parents were recruited into cessation support through their children's primary schools. After the baseline assessment, smoking parents were randomly assigned to tailored telephone counselling or a standard self-help brochure. Parental cessation was measured as 6-month prolonged abstinence at the 12-month follow-up. Children's smoking-related cognitions and smoking initiation were examined at 3-month, 12-month, and 30-month follow-up.

RESULTS

No statistical evidence was found that children of parents who received telephone counselling tailored to smoking parents or children of parents who achieved prolonged abstinence differ in smoking-related cognitions (i.e., smoking outcome expectancies, perceived safety of smoking, self-efficacy to refrain from smoking, susceptibility to smoking) or smoking initiation rate on any follow-up assessment.

CONCLUSIONS

This study is the first to examine the effects of an evidence-based smoking cessation treatment for parents and treatment-induced parental smoking cessation on cognitive and behavioural outcomes among children. Although descriptive statistics showed lower smoking initiation rates among children of parents who achieved prolonged abstinence, there was no statistical evidence that telephone counselling tailored to parents or treatment-induced parental smoking cessation affects precursors of smoking or smoking initiation among youth.

A systematic review of self-medication practices among adolescents

The purpose was to systematically review the global trends and factors influencing self-medication (SM) among adolescents. Databases (Medline/Pubmed, Ingenta, Cochrane Library, EMBASE, CINAHL, Proquest, Scopus, and Google Scholar) were searched for peer-reviewed research published between January 2000 and December 2013 on SM among adolescents aged 13-18 years. Articles were scrutinized for country of origin, sample size, recall period, prevalence rates and associations, influencing factors, medicines used, self-medicated health complaints, sources of drug information, recommendation and procurement, knowledge about medicines, and adverse drug reactions. One hundred and sixty-three publications met the inclusion criteria. SM prevalence ranged from 2% to 92% in different countries. The most frequently self-medicated over-the-counter and prescription-only medicines were analgesics and antibiotics, respectively. Headache, allergies, and fever were the most common self-medicated health complaints reported. Misuse of both over-the-counter and prescription-only medicines reflected a risky trend. Female gender, older age, maternal education, and familial practices were associated with SM among adolescents. The primary sources of drug information, recommendation, and procurement included pharmacists, parents, and friends. High-risk practices such as diversion of prescription medicines and utilization of previous prescriptions were also reported. Most studies revealed gaps in drug knowledge, although adolescents self-rated it as satisfactory. However, few adverse drug reactions were reported, probably because of lack of awareness about the potential harmful effects of medicines. Recommendations for "responsible SM" have been made to minimize the adverse effects of SM. Understanding the links between various factors promoting SM can be helpful in deriving strategies aimed at reducing drug-related health risks among adolescents. Moreover, these will aid in creating awareness among adolescents about the potential risks of using drugs without proper information and consultation. Studies need to be designed to assess the changing trend and identify new correlates of self-medication practices among adolescents, which pose fresh challenges to monitor the menace.

Eye-tracking measures reveal how changes in the design of aided AAC displays influence the efficiency of locating symbols by school-age children without disabilities

PURPOSE Many individuals with communication impairments use aided augmentative and alternative communication (AAC) systems involving letters, words, or line drawings that rely on the visual modality. It seems reasonable to suggest that display design should incorporate information about how users attend to and process visual information. The organization of AAC symbols can influence the speed and accuracy with which children select a target symbol on a display. This research examined why some displays facilitate responding. METHOD Eye-tracking technology recorded point-of-gaze while children without disabilities engaged in a visual search task with 2 AAC displays. In 1 display, symbols sharing an internal color were clustered together. In the other display, like-colored symbols were distributed. Dependent measures were (a) latency to fixate on the target compared with distracters and (b) the number of fixations to target and distracters. RESULTS Participants were significantly slower to fixate on the target when like-colored symbols were distributed; there was a significant increase in the number of fixations to distracters that did not share color with the target. CONCLUSIONS Efficient search was related to minimizing fixations to nonrelevant distracters. Vulnerability to distraction can be a significant problem in individuals with disabilities who use AAC. Minimizing the intrusion of such distraction may, therefore, be of importance in AAC display design.

Environmental smoking and smoking onset in adolescence: the role of dopamine-related genes. Findings from two longitudinal studies

Although environmental smoking (i.e., paternal and maternal smoking, sibling smoking, and peer smoking) is one of the most important factors for explaining adolescent smoking behavior, not all adolescents are similarly affected. The extent to which individuals are vulnerable to smoking in their environment might depend on genetic factors. The aim of this study was to examine the interplay between environmental smoking and genes encoding components of the dopaminergic system (i.e., dopamine receptor D2, D4, and dopamine transporter DAT1) in adolescent smoking onset. Data from two longitudinal studies were used. Study 1 consisted of 991 non-smoking early adolescents (mean age = 12.52, SD = .57) whereas study 2 consisted of 365 non-smoking middle to late adolescents (mean age = 14.16, SD = 1.07) who were followed for 16 and 48 months, respectively. Logistic regression analyses were conducted using Mplus. In study 1, we found positive associations between parents' and friends' smoking at the first measurement and smoking status 16 months later. In study 2 we found a positive association between friends' smoking and smoking onset 48 months later. Neither study demonstrated any interaction effects of the DRD2, DRD4, or DAT1 genotypes. In conclusion, the effects of environmental smoking on smoking onset are similar for adolescent carriers and non-carriers of these specific genes related to the dopaminergic system.

Responses to environmental smoking in never-smoking children: can symptoms of nicotine addiction develop in response to environmental tobacco smoke exposure?

A recent line of studies has brought attention to the question whether repeated exposure to environmental tobacco smoke (ETS) is capable of producing psycho-physiological effects in non-smokers and whether symptoms of nicotine dependence can develop in the absence of active smoking. Children seem to be particularly vulnerable to the effects of ETS. We examined the occurrence of psycho-behavioural symptoms, designed to assess nicotine addiction and nicotine withdrawal, in a sample of 778 never-smoking children aged 9-12 years using cross-sectional survey data collected in 15 Dutch primary schools. In the present study, 6% of never-smoking children reported symptoms of craving, 8% reported cue-triggered wanting to smoke, and 20% reported subjective symptoms in response to ETS exposure. In never-smoking children, a higher number of smokers in the child's social environment was associated with more symptoms of cue-triggered wanting to smoke and more subjective symptoms in response to ETS. Never-smoking children and children who had initiated smoking were equally likely to report subjective symptoms in response to ETS exposure. In conclusion, environmental smoking is associated with self-reported psycho-behavioural symptoms in never-smoking children. Future research needs to investigate whether symptoms in children exposed to ETS are physiologically based or whether they reflect other characteristics which predispose youth for smoking initiation in the future.

Increasing use of nonmedical analgesics among younger cohorts in the United States: a birth cohort effect

PURPOSE

Nonmedical use of prescription pain drugs (hereafter "analgesics") has increased substantially in recent years. It is not known whether today's youth are disproportionately driving this increase or, instead, the trend is a general one that has affected cohorts of all ages similarly. To address this question we present the first age-period-cohort analysis of nonmedical use of analgesics.

METHODS

Data come from the National Survey on Drug Use and Health, a series of annual, nationally representative, cross-sectional surveys of the US civilian, noninstitutionalized population. The analysis focuses on the years 1985-2009 and uses the recently developed "intrinsic estimator" algorithm to disentangle age-period-cohort effects.

RESULTS

Substantial increases in the prevalence of nonmedical analgesics use (NAU) have occurred across all cohorts and ages in recent years, but this increase is significantly amplified among today's adolescents. The odds of past-year NAU for today's youngest cohort (born 1980-1994) are higher than would be expected on the basis of their age and broad, historical period influences that have increased use across people of all ages and cohorts. The independent influence of cohort on past-year NAU is about 40% higher for today's youth cohort than any of the cohorts that came before them. This finding is present among men, women, non-Hispanic whites, non-Hispanic blacks, and Hispanics.

CONCLUSIONS

Although nonmedical use of analgesics is evident among all ages, cohorts, and periods, today's younger cohorts warrant special attention for substance abuse policies and interventions targeted at reversing the increase in NAU.
