Effect sizes and effect size benchmarks in family violence research.

Scholarly journals increasingly request that authors include effect size (ES) estimates when reporting statistical results. However, there is little guidance on how authors should interpret ESs. Consequently, some authors do not provide ES interpretations, or, when interpretations are provided, they often fail to use appropriate reference groups, using instead the ES benchmarks suggested by Cohen (1988). After discussing the most commonly used ES estimates, we describe the method used by Cohen (1962) to develop ES benchmarks (i.e., small, medium, and large) for use in power analyses and describe the limitations associated with using these benchmarks. Next, we establish general benchmarks for family violence (FV) research. That is, we followed Cohen's approach to establishing his original ES benchmarks using family violence research published in 2021 in Child Abuse & Neglect, which produced a medium ES (d = 0.354) that was smaller than Cohen's recommended medium ES (d = 0.500). Then, we examined the ESs in different subspecialty areas of FV research to provide benchmarks for contextualized FV ESs and to provide information that can be used to conduct power analyses when planning future FV research. Finally, some of the challenges to developing ES benchmarks in any scholarly discipline are discussed. For professionals who are not well informed about ESs, the present review is designed to increase their understanding of ESs and what ES benchmarks tell them (and do not tell them) with respect to understanding the meaningfulness of FV research findings.

Does the Fading Affect Bias Vary by Memory Type and a Parent's Risk of Physically Abusing a Child? A Replication and Extension.

Research described in the present article assessed (a) whether a fading affect bias (FAB) occurred in parent memories of a child as well as parent general personal memories and (b) whether either or both of these FAB effects was moderated by a parent's risk of physically abusing a child. A FAB effect, unmoderated by parents' abuse risk status, emerged for parents' general personal memories. In contrast, the FAB was muted when high abuse risk parents remembered child-related events: High abuse risk parents seemed unable to "let go" of negative affect prompted by recall of negative events involving their children. This finding replicates and extends findings reported in prior research. However, this significant moderation effect occurred for only one event memory collection method. This methodological dependence is unusual: the FAB effect is typically impervious to methodological variations. Implications of these results, as well as suggestions for future research, are discussed.

Prolonged Infant Crying: Caregiving Quality and Child Physical Abuse Risk.

Research suggests that prolonged infant crying may increase risk for child physical abuse (CPA). However, few studies have examined behavioral responses to infant crying among parents at risk for CPA. The present study sought to fill this gap by using a simulated infant to examine how mothers and fathers with varying degrees of CPA risk respond to prolonged infant crying. Specifically, a sample of 184 general population caregivers (107 mothers and 77 fathers) participated in a task that involved attempting to soothe a simulated infant that cried continuously for 30 min. The simulated infant sessions were video-recorded, and quality of caregiving behavior was coded in 5-min segments. Participants rated their negative affect (feelings of upset, distress, irritability) at the outset of the data collection session, before beginning the simulated infant task, and after the simulated infant task concluded. It was predicted that high-risk caregivers, compared to low-risk caregivers, would display lower quality caregiving, higher levels of negative affect, and that CPA risk group differences would increase over time. Gender differences were explored in relation to the aforementioned hypotheses. Over the course of the 30-min simulated infant task, the quality of caregiving behavior diminished among both high- and low-risk caregivers. As expected, high-risk caregivers, compared to low-risk caregivers, exhibited lower quality caregiving behaviors and were more likely to discontinue the simulated infant task early. In addition, high-risk, compared to low-risk, caregivers reported higher levels of negative affect throughout the data collection session, with the highest level of negative affect reported by high-risk caregivers after completing the simulated infant task. Overall, the quality of caregiving exhibited by men and women did not significantly differ. The present findings highlight the importance of early intervention designed to support caregivers' abilities to respond effectively to prolonged infant crying.

Do High-Risk Parents Use More Aggression During Competitive Play With Children?

The present study examined the extent to which the aggressive tendencies of parents at risk for perpetrating child physical abuse (CPA) generalize to situations other than discipline-related encounters (e.g., a competitive gaming interaction). Participants included parents who were either low (n = 90) or high (n = 75) risk for CPA. Parents were led to believe that they were playing a game against a child opponent with whom they exchanged sound blasts of varying intensities. Parental sound blast selections served as a proxy for aggressive behavior. Parents were randomly assigned to high or low loss conditions. The fictitious child opponent's responses were pre-programed so that sound blasts received by parents became louder (i.e., more provocative) over time. As predicted, high CPA risk parents exhibited higher levels of aggression than low CPA risk parents. Moreover, high-risk parents reported having higher levels of aggressive motives during the game than low-risk parents; and aggressive motives explained the link between parental CPA risk and parents' aggressive behavior. With one exception, higher levels of child provocation during the game prompted parents to send higher levels of sound blasts. The exception to this pattern occurred among low-risk parents who experienced high rates of loss during the game. Specifically, low-risk parents in the high loss condition continued to send low levels of sound blasts even as their child opponent became more provocative. Aggressive motives (and the ability to change motives as situations change) may help explain differences in aggressive tendencies evinced by parents with varying levels of CPA risk.

Perceived Executive Functioning in Parents at Risk for Child Physical Abuse.

Research suggests that deficits in executive functioning are associated with negative parenting behaviors. However, limited research has examined the link between executive functioning and risk for child physical abuse (CPA) perpetration. Early studies examining executive functioning in parents at risk for perpetrating CPA relied on performance-based measures, which are designed to occur under carefully controlled conditions and may not capture difficulties experienced under less optimal conditions (e.g., during chaotic caregiving situations). Moreover, prior studies examining executive functioning in parents at risk for perpetrating CPA have relied on small samples comprised of only mothers. To advance our understanding of the linkage between executive functioning and CPA risk, the present study examined perceived deficits in executive functioning in a sample of general population mothers and fathers (N = 98) using a standardized self-report measure of executive functioning, namely, the adult version of the Behavior Rating Inventory of Executive Function (BRIEF-A). Parents were classified as low CPA risk or high CPA risk using the Child Abuse Potential Inventory. Compared with low-risk parents, high-risk parents had higher rates of clinical elevations on several BRIEF-A subscales, namely, Working Memory Problems, Emotional Control Difficulties, and Difficulties Shifting Thoughts, Feelings, and Behaviors. These findings highlight the potential importance of assessing and strengthening executive functioning in interventions designed to reduce risk of parent-to-child aggression.

Exploring Positive Classical Conditioning Procedure Effects on Evaluations of Children, Thoughts About Children, and Behaviors Toward Children: Two Experiments.

Exposing parents to a positive classical conditioning (+CC) procedure can (a) prompt positive evaluations of children, (b) alter judgments made about children from their behavior, and (c) reduce harsh behaviors enacted toward children. Two studies explored possible limits of these effects. Results from Study 1 showed that only some +CC effects evinced in prior research emerged when the positive trait words used as the unconditioned stimuli in prior research were replaced with positive emojis. Results from Study 2 showed with positive trait word stimuli that a backward +CC procedure produced many of the same effects produced by the forward +CC procedure. These results collectively support the idea that +CC procedures may simultaneously prompt several different kinds of learning. From a practical perspective, consideration of these various kinds of learning is important to an understanding of when the use of the +CC procedure might reduce child abuse risk.

Child-related attributions of hostile intent and harsh discipline: Moderating effects of anger.

Two studies tested whether attributions of hostile intent (AHI) and anger for ambiguous child behaviors uniquely predict parents' harsh verbal discipline (HVD) and harsh physical discipline (HPD) or whether AHI only predicts harsh discipline when AHI occurs in conjunction with anger, as suggested by the Integrated Cognitive Model of general aggression (Wilkowski & Robinson, 2010, J. Pers., 78, 9-38). Replicating previous studies, the expected positive bivariate relationships between AHI, anger, HVD, and HPD were found in Study 1 (N = 493). However, when AHI, anger, and the AHI by anger interaction were considered simultaneously, patterns of prediction varied by discipline type. For HVD, high levels of AHI, high levels of anger, and the AHI by anger interaction (at high levels of AHI and anger) each were significant predictors. For HPD, low levels of AHI, high levels of anger, and the AHI by anger interaction (at high levels of AHI and anger) were significant predictors, suggesting a possible suppressor effect for AHI. These results were replicated in Study 2 ( N = 503). Thus, there was support for the contention that AHI only predicts harsh discipline when AHI occurs in conjunction with anger with respect to HPD but this was not the case for HVD. Since AHI suppressor effects were observed for HPD in two large sample studies, variables that may account for the AHI suppressor effects and the need for testing more complex interactive predictive models of harsh parenting behaviors are discussed.

Do emotion regulation difficulties explain the association between executive functions and child physical abuse risk?

This study examined the associations between executive functioning problems, emotion regulation difficulties, and risk for perpetrating child physical abuse (CPA). It was hypothesized that: (a) poor executive functions (i.e., working memory problems and inhibition/switching problems) would be associated with higher levels of emotion regulation difficulties and CPA risk; (b) emotion regulation difficulties would be positively associated with CPA risk; and (c) emotion regulation difficulties would partially explain the association between executive functions (i.e., working memory problems and inhibition/switching problems) and CPA risk. To examine these predictions, a sample of 133 general population parents (31% fathers) completed self-report measures of CPA risk, emotion regulation difficulties, working memory problems, and a performance-based measure of inhibition/switching skills. Results revealed that executive functioning problems were linked with emotion regulation difficulties, which in turn were associated with CPA risk. Moreover, emotion regulation difficulties explained the relationship between executive functions (working memory, inhibition/switching) and CPA risk. The final model accounted for 41% of the variance in CPA risk. Although additional research is needed, the present findings suggest that enhancing parents' executive functioning and teaching them effective emotion regulation skills may be important targets for CPA prevention efforts.

Heart Rate and Heart Rate Variability in Parents at Risk for Child Physical Abuse.

The present study examined heart rate and heart rate variability (i.e., respiratory sinus arrhythmia [RSA]) in a sample of 48 general population parents (41.7% fathers), who were either at high risk (n = 24) or low risk (n = 24) for child physical abuse. During baseline assessments of heart rate and RSA, parents sat quietly for 3 min. Afterward, parents were presented with a series of anagrams (either easy or difficult) and were instructed to solve as many anagrams as possible in 3 min. As expected, high-risk (compared with low-risk) parents evinced significantly higher resting heart rate and significantly lower resting RSA. During the anagram task, high-risk parents did not evince significant changes in heart rate or RSA relative to baseline levels. In contrast, low-risk parents evinced significant increases in heart rate and significant decreases in RSA during the anagram task. Contrary to expectations, the anagram task difficulty did not moderate the study findings. Collectively, this pattern of results is consistent with the notion that high-risk parents have chronically higher levels of physiological arousal relative to low-risk parents and exhibit less physiological flexibility in response to environmental demands. High-risk parents may benefit from interventions that include components that reduce physiological arousal and increase the capacity to regulate arousal effectively.

Parents' spontaneous evaluations of children and symbolic harmful behaviors toward their child.

Parents' evaluations of children are believed to be a cognitive contributor to their subsequent child-directed harsh or physically abusive behaviors. The current research examined whether parents' (N=100) evaluations of children were moderated by either (a) the child behavior on which the evaluation was based and (b) parents' measured risk for child physical abuse. The study also explored whether parents' evaluations of children were related to their tendencies to symbolically harm their child. The current study also used a novel method to indirectly assess parents' evaluations of children: A modified Affect Misattribution Procedure. Contrary to a priori expectations, negative evaluations of children were stronger for parents who were at low risk, relative to high risk, for child physical abuse. Nonetheless, we observed that high-risk parents were more likely than low-risk parents to inflict symbolic harm onto their child. In an exploratory analysis we observed that parents who formed more overall negative evaluations of children engaged in more symbolic harm to their child. Although high-risk parents were more likely to symbolically harm their child than low-risk parents, this effect does not seem to be due to high-risk parents' negative child evaluations from negative child behaviors.

Do hostile attributions and negative affect explain the association between authoritarian beliefs and harsh parenting?

The present study examined the associations between authoritarian parenting beliefs, attributions of hostile intent, negative affect, and harsh parenting practices. General population parents (N=183; 31.1% fathers) completed self-report measures of authoritarian parenting beliefs and read vignettes describing children engaging in transgressions. Following each vignette, parents indicated the extent to which they would attribute hostile intent to the child, feel negative affect, and respond with harsh parenting practices (e.g., yelling, hitting). As hypothesized, parents who subscribed to higher levels of authoritarian beliefs attributed more hostile intent to the child and expected to feel more negative affect in response to the transgressions. In turn, higher levels of hostile attributions and negative affect were associated with increased likelihood of harsh parenting practices. Results from a path analysis revealed that the association between authoritarian parenting beliefs and harsh parenting practices was fully explained by attributions of hostile intent and negative affect.

Baseline Functioning and Stress Reactivity in Maltreating Parents and At-Risk Adults: Review and Meta-Analyses of Autonomic Nervous System Studies.

We reviewed and meta-analyzed 10 studies ( N = 492) that examined the association between (risk for) child maltreatment perpetration and basal autonomic activity, and 10 studies ( N = 471) that examined the association between (risk for) child maltreatment and autonomic stress reactivity. We hypothesized that maltreating parents/at-risk adults would show higher basal levels of heart rate (HR) and skin conductance (SC) and lower levels of HR variability (HRV) and would show greater HR and SC stress reactivity, but blunted HRV reactivity. A narrative review showed that evidence from significance testing within and across studies was mixed. The first set of meta-analyses revealed that (risk for) child maltreatment was associated with higher HR baseline activity ( g = 0.24), a possible indication of allostatic load. The second set of meta-analyses yielded no differences in autonomic stress reactivity between maltreating/at-risk participants and nonmaltreating/low-risk comparison groups. Cumulative meta-analyses showed that positive effects for sympathetic stress reactivity as a risk factor for child maltreatment were found in a few early studies, whereas each subsequently aggregated study reduced the combined effect size to a null effect, an indication of the winner's curse. Most studies were underpowered. Future directions for research are suggested.

Validating the Voodoo Doll Task as a Proxy for Aggressive Parenting Behavior.

OBJECTIVE: Six studies (N = 1,081 general population parents) assessed the validity of the Voodoo Doll Task (VDT) as a proxy for aggressive parenting behaviors. METHODS: Participants were given an opportunity to symbolically inflict harm by choosing to stick "pins" into a doll representing their child. RESULTS: Individual differences in parents' trait aggression (Studies 1, 2, and 6), state hostility (Study 3), attitudes towards the corporal punishment of children (Study 4), self-control (Study 6), depression (Study 6), and child physical abuse risk (Study 6) were associated with increased pin usage. Further, parents used more pins after imagining their child perform negative behaviors compared to after imagining their child perform positive behaviors (Study 5). A number of demographic variables also were associated with pin usage: Fathers used pins more than mothers and parents' education level was inversely related to pin usage. Finally, on average, parents viewed the VDT as slightly uncomfortable, but not objectionable, to complete (Study 6). CONCLUSIONS: Our evidence suggests that the VDT may serve as a useful proxy for parent-to-child aggression.

Borderline personality features and emotion regulation deficits are associated with child physical abuse potential.

The present study extends prior research examining the association between borderline personality disorder (BPD) features and child physical abuse (CPA) risk. We hypothesized that: (1) high CPA risk parents (compared to low CPA risk parents) would more often report clinically elevated levels of BPD features; (2) high CPA risk parents with elevated BPD features would represent a particularly high-risk subgroup; and (3) the association between elevated BPD features and CPA risk would be partially explained by emotion regulation difficulties. General population parents (N=106; 41.5% fathers) completed self-report measures of BPD features, CPA risk, and emotion regulation difficulties. Results support the prediction that BPD features are more prevalent among high (compared to low) CPA risk parents. Among the parents classified as high CPA risk (n=45), one out of three (33.3%) had elevated BPD features. In contrast, none of the 61 low CPA risk parents reported elevated BPD symptoms. Moreover, 100% of the parents with elevated BPD features (n=15) were classified as high-risk for CPA. As expected, high CPA risk parents with elevated BPD features (compared to high CPA risk parents with low BPD features) obtained significantly higher scores on several Child Abuse Potential Inventory scales, including the overall abuse scale (d=1.03). As predicted, emotion regulation difficulties partially explained the association between BPD features and CPA risk. Findings from the present study suggest that a subset of high CPA risk parents in the general population possess clinically significant levels of BPD symptoms and these parents represent an especially high-risk subgroup. Interventions designed to address BPD symptoms, including emotion regulation difficulties, appear to be warranted in these cases.

Pain tolerance, pain sensitivity, and accessibility of aggression-related schemata in parents at-risk for child physical abuse.

This study examined whether parents with varying degrees of child physical abuse (CPA) risk differed in pain tolerance, pain sensitivity, and accessibility of aggression-related schemata. Participants included 91 (51 low CPA risk and 40 high CPA risk) general population parents. Participants were randomly assigned to complete either an easy or a difficult anagram task. Pain tolerance and pain sensitivity were assessed using a cold pressor task. Accessibility of aggression-related schemata was assessed at the outset of the data collection session and at the end of the session using a word completion task. Parents' self-reported negative affect was assessed three times over the course of the study: baseline, after the anagram task, and after the cold pressor task. As expected, high-risk (compared to low-risk) parents reported higher levels of negative affect at each time point. Moreover, after completing the difficult anagram task, high-risk (compared to low-risk) parents exhibited higher pain sensitivity during the cold pressor task. Following completion of the cold pressor task, high-risk (compared to low-risk) parents exhibited greater accessibility of aggression-related schemata. Collectively, these findings indicate that under certain conditions, high-risk parents experience a confluence of aggression-related risk factors (i.e., negative affect, pain sensitivity, and aggression-related information processes) that may predispose them to aggressive behavior.

Reactions to children's transgressions in at-risk caregivers: does mitigating information, type of transgression, or caregiver directive matter?

This study examined whether caregivers who exhibit high risk for child physical abuse differ from low-risk caregivers in reactions to transgressing children. Caregivers read vignettes describing child transgressions. These vignettes varied in: (a) the type of transgression described (moral, conventional, personal), (b) presentation of transgression-mitigating information (present, absent), and (c) whether a directive to avoid the transgression was in the vignette (yes, no). After reading each vignette, caregivers provided ratings reflecting their: (a) perceptions of transgression wrongness, (b) internal attributions about the transgressing child, (c) perceptions of the transgressing child's hostile intent, (d) own expected negative post-transgression affect, and (e) perceived likelihood of responding to the transgression with discipline that displayed power assertion and/or induction. For moral transgressions (cruelty, dishonesty, hostility, or greed), mitigating information reduced caregiver expectations that they would feel negative affect and, subsequent to the transgression, use disciplinary strategies that display power assertion. These mitigating effects were smaller among at-risk caregivers than among low-risk caregivers. Moreover, when transgressions disobeyed a directive, among low-risk caregivers, mitigating information reduced the expectation that responses to transgressions would include inductive disciplinary strategies, but it did not do so among at-risk caregivers. In certain circumstances, compared to low-risk caregivers, at-risk caregivers expect to be relatively unaffected by transgression-mitigating information. These results suggest that interventions that increase an at-risk caregiver's ability to properly assess and integrate mitigating information may play a role in reducing the caregiver's risk of child physical abuse.

Child physical abuse risk moderates spontaneously inferred traits from ambiguous child behaviors.

The present study examined whether parents at high-risk for child physical abuse (CPA) differed from low-risk parents in their tendency to infer positive traits and negative traits from children's behaviors. The final sample consisted of 58 (25 low CPA risk and 33 high CPA risk) parents. Parents completed a false-recognition task, which involved viewing behavior descriptions paired with child photographs. Half of the behavior descriptions vaguely/strongly implied a trait and half of the implied traits were positive/negative. The contributions of automatic processes and controlled processes to task performance were examined using process dissociation procedures. Low CPA risk parents were significantly less likely to indicate negative traits were present in behavioral descriptions of children when negative traits were vaguely (compared to strongly) implied. In contrast, high CPA risk parents were equally likely to indicate negative traits were present regardless of whether the traits were vaguely or strongly implied. For low (but not high) CPA risk parents, automatic processes contributed significantly less to task performance when negative traits were vaguely implied compared to when the same traits were strongly implied. Given that parenting involves negotiating a seemingly endless series of ambiguous behaviors as children grow and develop, the capacity to refrain from automatically attributing negative traits to children when they exhibit vaguely negative behaviors may serve an important function in reducing risk of aggressive parenting behavior.

The Word Game: an innovative strategy for assessing implicit processes in parents at risk for child physical abuse.

OBJECTIVE: Contemporary theories of child physical abuse (CPA) emphasize the proximal role of social cognitive processes (many of which are implicit in nature) in the occurrence of parental aggression. However, methods that allow for the systematic examination of implicit cognitive processes during the course of aggressive interactions are needed. To address this need, the present study was designed to examine the utility of the Word Game, an innovative procedure designed to assess implicit changes in schema accessibility during the course of an interpersonal exchange involving aggressive response options. METHODS: The game involves a series of competitive reaction time trials which are actually lexical decision making trials designed to determine the accessibility of schema throughout the game. Each parent was led to believe that they were competing against another player with whom they exchanged sound blasts of varying intensities. Participants in the present study were parents who were either low (n=50) or high (n=20) risk for CPA. RESULTS: Results revealed that high CPA risk parents behaved more aggressively than low CPA risk parents and that provocation augmented the aggressiveness of all participants. Among high CPA risk parents, positive schema became less accessible (whereas negative schema became more accessible) following lost rounds. At the conclusion of the game, high CPA risk parents reported more aggressive motives than low CPA risk parents. Further, aggressive motives significantly mediated the association between CPA risk status and aggressiveness (i.e., mean sound blast selections). CONCLUSIONS: Collectively, results support the potential utility of the Word Game as a means of advancing the study of social cognitive processes involved in parental aggression.

Evaluation of a sexual assault education/prevention program for female U.S. Navy personnel.

The U.S. Navy Sexual Assault Intervention Training (SAIT) program for women was evaluated in a randomized clinical trial. The SAIT uses multiple presentation modalities (lecture, slides, discussion, film) to provide information related to sexual assault, including risk factors, consequences, prevention, and relevant military regulations. Female personnel who had completed basic training (N = 550) participated in the SAIT or a Comparison condition, and then completed measures of rape knowledge, empathy for rape victims, and acceptance of rape myths (false beliefs about rape justifying sexual violence). Results showed that the SAIT increased factual knowledge about rape. In addition, the SAIT increased empathy with rape victims in some groups of women. However, the program did not reduce women's rape myth acceptance. Given the enormity of the problem of sexual assault and these promising initial findings, additional research on the efficacy of the SAIT is clearly warranted.
