“Childhood trauma can cause children to feel anxious, disconnected, and distrustful, and these effects can complicate their adjustment to new homes.”

Results supported the central hypotheses that individuals with higher levels of childhood maltreatment (CM) show more distrust and negatively shifted emotion ratings. The study tested 549 participants and found that higher levels of CM entailed greater distrust and perceived threat, with distrust being more change-resistant in participants with more CM. These cognitive alterations—increased distrust and perceived interpersonal threat—are similar to those proposed in cognitive models of PTSD.

Reporting emotional abuse (Odds ratio OR from 2.14 to 14.71), emotional neglect (OR from 2.42 to 10.99), or physical neglect (OR from 2.24 to 3.30) was associated with reporting anxiety and long-term pain both in the general and clinical populations. The study highlights the relevance of various types of childhood trauma as possible factors contributing to anxiety and pain-related conditions in adulthood in both the general and clinical populations.

Children and adolescents with developmental trauma disorder may react with either over-modulated or under-modulated behaviors. Over-modulated children appear hyperactive and aggressive, whereas under-modulated children appear depressed, withdrawn, and possibly dissociative. They may be highly reactive to their environment (e.g., hypersensitive to sounds, touch, lights) or appear to be relatively indifferent to their immediate surroundings. They may react to perceived threats with avoidance, tantrums, or anger, especially when they feel emotionally vulnerable or disempowered.

There was evidence to suggest a relationship with internalising behaviours, and mental health difficulties, in particular PTSD symptoms. Placement instability predicted internalising behaviour difficulties from baseline to 18 months for boys only (small effect size) and at 18–36 months for girls only (medium-large effect size). The review highlights that instability seems to result in negative psychological outcomes, although the extent of this relationship remains unclear.

Caregiver-perpetrated trauma (CPT) is associated with adverse consequences for youth, including out-of-home placement. A wide range of impairments were compared, including PTSD symptoms, internalizing and externalizing behaviors, and attachment problems. The primary hypothesis was that children in foster care would exhibit greater posttraumatic stress symptoms, internalizing and externalizing problems, and attachment problems compared to children in kinship care.

Children who experience maltreatment often develop anxiety, distrust of caregivers, and difficulty with emotional regulation. These effects can complicate their adjustment when placed in new homes, as they may struggle to form secure attachments with new caregivers and may exhibit hypervigilance and avoidant behaviors.

In our sample of adults, levels of insecure attachment differed between those with and without self-reported histories of childhood maltreatment, such that insecure attachment was more common in those reporting high maltreatment levels. This finding is not surprising; attachment insecurity, an expected response to abuse in early life, constitutes a vivid example of the influence that early trauma has on later social functioning.

On the other hand, exposure to trauma in early childhood significantly interferes with the ability to form secure attachments. Despite experiencing trauma such as neglect and abusive behavior, however, all children continue seeking proximity and develop distinct attachment patterns.

Elementary school children who have experienced trauma may exhibit anxiety, guilt, shame, lack of concentration, difficulty sleeping, withdrawal or disinterest, and aggression. These symptoms reflect the emotional and behavioral disruptions that trauma can cause in children's functioning.

Children and teens with PTSD may become withdrawn, numb, and lacking in emotion expression, including positive ones. Acting helpless or hopeless is also possible. These emotional and behavioral changes can significantly impact their social functioning and ability to adapt to new situations.

Traumatized children may experience anxiety, fear, and difficulty trusting others. These symptoms can persist and interfere with their ability to form new relationships and adjust to changes in their environment, such as placement in new homes or foster care settings.

Children may experience trauma-related avoidance, low motivation, hopelessness, distrust, shame, guilt, or fear of not being believed. At a neurobiological level, the brain becomes more aware of potential threats. At the psychological level, the traumatic experiences are encoded in autobiographical memories to minimise future threats. At the social level, the threats in the environment may lead to withdrawal and reduction in social connections.

Children who do not have healthy attachments have been shown to be more vulnerable to stress. They have trouble controlling and expressing emotions, and may experience difficulty with emotional regulation, which can affect their ability to adjust to new environments and relationships.

Symptoms of trauma and stressor-related disorders in children may include jumpiness, sleep problems, problems in school, avoidance of certain places or situations, depression, headaches or stomach pains. These symptoms can interfere with a child's ability to function in new environments and relationships.

If someone experiences trauma as a child, it can lead to physical and mental struggles that affect their entire life. Childhood trauma impacts emotional regulation, social functioning, and the ability to form secure attachments, which are critical for adjustment to new environments.

Children with clinically significant trauma symptoms had 46% higher odds of placement instability (defined as three or more foster care placements). This study reveals trauma symptoms as predictive of placement instability even while controlling for demographic and case characteristics, underscoring trauma screening and intervention as important steps toward addressing trauma's influence on children's trajectories in foster care.

Trauma in young children can disrupt multiple developmental domains. In the attachment domain, children may show difficulty trusting others, uncertainty about the reliability and predictability of others, interpersonal difficulty, social isolation, and difficulty seeking help. In affect regulation, children may have problems with emotional regulation, be easily upset with difficulty calming, and have difficulty describing emotions and internal experiences.

The reviewed literature reveals a consistent association between childhood trauma and the development of insecure attachment patterns, emotional dysregulation, and diminished relational well-being. Insecure attachment and impaired emotion regulation were frequently identified as key mediators between early trauma and adult relational difficulties. Childhood trauma tend to develop maladaptive attachment styles due to early disruptions in emotional bonding. The data supports the idea that these individuals are more likely to have insecure attachment styles, which complicates their ability to trust and form stable, intimate relationships.

Multiple placements for foster youth result in developmental challenges for children. Research shows correlation between negative development outcomes and placement instability. The research provided social workers with knowledge of the emotional interruptions youth face with each transition made, including behavioral responses to trauma such as anxiety and disconnection.

Traumatized children often show extreme separation anxiety and clinginess, emotional dysregulation with frequent meltdowns, fear responses and heightened startle, hypervigilance and constant scanning for danger, negative beliefs about themselves and the world (e.g., 'It was my fault,' 'I can't trust anyone,' 'The world isn't safe'), social withdrawal and friendship difficulties, and emotional numbing where they seem emotionally flat or detached.

Placement instability, as well as placement in group home settings, contributed to higher rates of reoffending and negative outcomes. Results showed significant correlations between negative safety experiences and negative esteem experiences with negative outcomes, including trust and intimacy difficulties.

Bowlby's attachment theory and subsequent research demonstrate that early trauma disrupts secure attachment formation, leading to anxious, avoidant, or disorganized attachment styles. These insecure attachment patterns are associated with heightened anxiety, interpersonal distrust, and difficulty adjusting to new caregiving relationships—a particularly relevant concern for children transitioning to new homes.

Difficulty Forming Trusting Relationships: Trust is a foundational element of any healthy relationship, but for children who have been abused—especially by caregivers or authority figures—trust is often shattered. Abused children may be wary of others, fearing betrayal or harm. This mistrust can manifest in difficulty forming friendships, building attachments, or establishing intimate relationships in adulthood. Attachment Issues: Abuse can severely disrupt a child’s ability to form secure attachments with caregivers and others. Chronic Fear and Hypervigilance: Abuse fosters a sense of constant danger in children. Many abused children develop hypervigilance, an acute awareness of potential threats in their environment.

Difficulty Forming Friendships: Children with attachment trauma may struggle to make friends and are more susceptible to bullying. Behavioral Issues: Persistent uncooperative or aggressive behaviors can be a sign of underlying attachment trauma. Mental Health Impacts: Conditions like anxiety, depression, and mood disorders can be common in children with attachment trauma.

Most profoundly, attachment trauma shapes your sense of self and core beliefs. Children internalize messages from primary caregivers. If those messages are rejecting or harmful, you might develop negative self-beliefs like 'I'm not lovable' or 'I can't trust anyone.' These early experiences create neural pathways that influence our entire adult life, affecting our ability to form healthy relationships.

Attachment problems can affect your child's development, relationships, and overall well-being. Here's how to overcome insecure attachment.
