Increasing variety of foods consumed by blending nonpreferred foods into preferred foods

A treatment with differential or noncontingent reinforcement and nonremoval of the spoon increased the acceptance of one or two of 16 foods for 2 participants with severe food refusal. These differential levels of acceptance were demonstrated empirically in an ABAB design in which A was the presentation of the accepted (preferred) foods and B was the presentation of foods the participants refused (nonpreferred foods). Subsequently, we implemented a blending treatment that consisted of mixing (blending) nonpreferred foods into preferred foods in various ratios (e.g., 10% nonpreferred/90% preferred, 20% nonpreferred/80% preferred). We then presented nonpreferred foods that had been exposed to blending to determine if consumption of nonpreferred foods would increase following the blending treatment. We also conducted periodic reversals in which we presented nonpreferred foods that had not been exposed to the blending treatment. Following initial implementation of the blending treatment, consumption was high for nonpreferred foods that had been blended and low for nonpreferred foods that had not been blended. Consumption increased for all foods (i.e., foods that had been exposed to blending and foods that had not been exposed to blending) after seven or eight foods had been exposed to the blending treatment. Thus, the variety of foods consumed by the participants increased from one or two to 16. These results are discussed in terms of stimulus fading, conditioned food preferences, and escape extinction.

Using reinforcer pairing and fading to increase the milk consumption of a preschool child

The present study replicates and extends previous research on the treatment of food selectivity by implementing pairing and fading procedures to increase a child's milk consumption during regularly scheduled preschool meals. The treatment involved mixing a small amount of chocolate syrup into a glass of milk and gradually eliminating the chocolate. The procedure and data collection were implemented by preschool teachers and resulted in increased milk drinking at school, which was maintained at home.     

Acquisition of cup drinking using previously refused foods as positive and negative reinforcement

We used previously refused foods as positive and negative reinforcement in the acquisition of cup drinking. Cup drinking increased with positive and negative reinforcement, both alone and in combination (without escape extinction), indicating that treatment of food refusal can establish some foods as appetitive stimuli whereas others remain aversive.     

Evaluation of empirical pretreatment assessments for developing treatments for expulsion in pediatric feeding disorders

A common problem among children with feeding disorders is expulsion (removing or spitting food or drink from the mouth), which interferes with treatment success when the goal is consumption. Previous research has identified effective treatments to reduce expulsion, most commonly—re-presentation (presenting the expelled bite or a new bite of the same food immediately following the expulsion). However, there is not currently an assessment model in place to inform treatment decisions with a goal to reduce expulsion. In the present study, we used a multielement design to identify conditions under which little or no expulsion occurred with three children with feeding disorders. The results of the assessment were then used to inform treatment selection aimed to eliminate expulsion. The comparisons of the assessment included physical prompt, bite number, texture, preference, bite presentation style, and size of the bite. Results suggest that this assessment was useful for the design of individualized treatments for children who frequently expel food.     

COMBINING STIMULUS FADING,REINFORCEMENT, AND EXTINCTION TO TREAT FOOD REFUSAL

The food refusal of a 6-year-old girl with destructive behavior was treated using stimulus fading, reinforcement, and escape extinction. Intake increased and compliance with prompting procedures remained relatively stable despite the increased consumption requirement.     

A COMPARISON OF SIMULTANEOUS AND DELAYED REINFORCEMENT AS TREATMENTS FOR FOOD SELECTIVITY

This study compared the relative efficacy of providing simultaneous or delayed reinforcement on food acceptance during meals. The participant was a 7-year-old boy with pervasive developmental disorder and a history of food selectivity. Results indicated that both procedures were effective in increasing acceptance; however, the simultaneous reinforcement procedure produced more rapid behavior change and a higher overall percentage of food acceptance.     

AN ALTERNATING TREATMENTS COMPARISON OF TWO INTENSIVE INTERVENTIONS FOR FOOD REFUSAL

We compared two treatment packages involving negative reinforcement contingencies for 3 children with chronic food refusal. One involved physically guiding the child to accept food contingent on noncompliance, whereas the other involved nonremoval of the spoon until the child accepted the presented food. Subsequent to baseline, an alternating treatments comparison was implemented in a multiple baseline design across subjects. After each child had been exposed to at least nine sessions of each treatment condition and percentage of bites accepted had increased to at least 80%, the child's caregivers selected the preferred treatment package. The results indicated that both treatments were effective in establishing food acceptance. However, physical guidance was associated with fewer corollary behaviors, shorter meal durations, and parental preference.     

父母因素、抵制效能感与青少年新媒介依赖行为的关系

以500名青少年手机拥有者为被试,采用问卷调查法考察青少年新媒介依赖(包括网络和手机依赖)的特点,并探讨父母因素和抵制效能感对青少年新媒介依赖的预测作用。结果发现:(1)40%的青少年至少存在边缘网络成瘾行为,19.8%的青少年为手机依赖者。青少年网络成瘾和手机依赖这两种新媒介依赖行为间具有显著的关联性,46.4%的青少年存在至少一种新媒介依赖行为。(2)青少年新媒介依赖行为与其抵制效能感、父母行为/态度及父母行为监控显著相关。青少年抵制效能感在父母行为/态度与青少年新媒介依赖行为之间起到完全中介的作用,在父母行为监控与青少年新媒介依赖行为间起到部分中介的作用。研究结果对提高青少年新媒介依赖行为预防干预活动的有效性和针对性具有重要的指导意义。     

Childhood vaccine refusal and hesitancy intentions in Croatia: insights from a population-based study

Considering that programmatic data suggest a recent rise in vaccine refusal in Croatia, this study, first of its kind in Southeast Europe, aimed to estimate the prevalence, and sociodemographic, and sociocultural determinants of childhood vaccine refusal and hesitancy (CVRH) intentions among Croatian adults. Multi-stage stratified population-based survey included 1000 individuals aged 18–88 years (M_age = 47.7, SD = 17.8), of whom 51.7% were women. The outcome, a categorical indicator, distinguished among individuals who would approve vaccinating their children (vaccine accepting), those who would approve some but not all vaccines (vaccine hesitant), and those who would refuse vaccination (vaccine refusing). A sizeable minority of participants was characterized by childhood vaccine refusal (10.6%) and hesitancy intentions (19.5%). In a multivariate assessment controlling for parenthood, the odds of vaccine hesitancy were significantly increased by a younger age (AOR = 1.96–3.03, p < .01). Religiosity (AOR = 1.12, p < .05) and the use of alternative medicine (AOR = 2.85, p < .001) increased the odds of vaccine refusal. However, individual characteristics seem to be relatively poor predictors of CVRH intentions in Croatia. Following the social contagion model, future research should move beyond individual-level approach and take into account social interaction and social network effects.     

A theology of pastoral multiplicity

The contemporary moment is characterized by liquidity and difference. “Liquidity” means rapidly changing social structures, accelerations in consumption, and constantly changing personal and group identities. In this increasingly diverse context, encounters with difference are not only inevitable, they are essential—and can be transformative for our understandings of our multiple selves, for our pastoral encounters with others, and for our theological imagination, as well. Viewing the self, especially the pastor's self, as a collection of multiple selves, identities, and performances illumines pastoral leadership; pastors who claim their multiplicity more wholly meet “others” when encountering difference. The triune God reveals divine multiplicity, so pastors who claim their multiplicity as their identity thereby make a theological claim.
