C., et al., 2017): - Probability of encountering a traumatic event in a lifetime: 70.4% - Probability of developing PTSD in a lifetime: 4% There is a significant gap between trauma exposure and PTSD onset. Who is more likely to develop PTSD? 💫PTSD-Prone Individual Characteristics ①Attributes <Women> Compared to men: - Women are more likely to develop PTSD after experiencing the same trauma. - More likely to experience sexual violence, physical violence, or accidents. <Adolescents> - More likely to experience trauma involving violence or accidents. - Childhood trauma can trigger genetic vulnerabilities to PTSD. <Elderly> Individuals over 65 have a significantly higher probability of developing PTSD from traumatic experiences. 💫PTSD-Prone Individual Characteristics ②Experiences <ACEs (Adverse Childhood Experiences)> Influence brain development, epigenetics, and attachment styles, increasing PTSD risk and trauma exposure likelihood. Note: ACEs refer to traumatic events and complex family environments experienced before age 18. See previous posts for details. <Healthcare Workers> - Emergency responders have twice the risk of PTSD compared to the general population. - Estimated PTSD prevalence among healthcare workers is 17–29%, particularly during the COVID-19 pandemic. <Past Mental Health History> Individuals with a history of mental illness have a higher risk of developing PTSD than those without. 💫PTSD-Prone Individual Characteristics ③Environment <Lack of Psychosocial Resources> When individuals face ongoing stressors or have difficulty accessing social support, their risk of developing PTSD increases. <Economic Hardship> Low socioeconomic status or limited years of education can contribute to a lack of psychosocial resources, raising the risk of PTSD. ─── ⋆⋅☆⋅⋆ ──── Thank you so much for reading!

If you feel uncomfortable, please don't hesitate to stop reading. 💫Adverse Childhood Experiences (ACEs) What are ACEs? →Traumatic events or circumstances that occur before the age of 18. If four or more of the ten types of ACEs apply, individuals are more likely to face: - Mental health problems - Physical health problems - Unemployment - Crime 💫1. Physical Abuse - Actions that do not leave physical scars are also considered physical abuse. - Discipline or punishment may also be regarded as physical abuse in some cases. 💫2. Sexual Abuse - Not only direct actions but also exposing children to sexual content is considered sexual abuse. 💫3. Psychological Abuse - Primarily towards children, deliberately making them feel: - "I am worthless." - "I have flaws." - "I am not loved." - "I am unwanted." - "I am in danger." - "I am only valuable for fulfilling others' desires." - Isolating children from friends and family is also included. - Even without direct physical violence, showing threatening behavior is considered psychological abuse. 💫4. Physical Neglect - Not providing appropriate nutrition, hygiene, living environment, clothing, etc. - Hindering access to medical care and education is also included. 💫5. Psychological Neglect - Not responding to a child's emotional needs. For example, not reacting to an infant's cries or ignoring an older child's requests for attention. - Cases where a caregiver is aware of abuse by others but fails to protect the child are also included. 💫6. Witnessing Domestic Violence - If the caregiver is being abused by their partner and is either unable to take measures to protect the child or unaware of how to address the situation, such cases are not included. 💫7. Caregiver’s Substance Abuse - Abuse of alcohol, prescription drugs, or illegal substances etc. 💫8. Caregiver’s Mental Illness - A caregiver suffering from persistent depressive states, anxiety disorders, schizophrenia, eating disorders, or substance use disorders.

Let’s examine them in detail on the next slides. 😺Complex trauma refers to prolonged, repeated exposure to trauma in an environment that is difficult to escape. See previous posts for more details. 💫Disturbances of Self-Organization - Difficulties in emotional regulation Emotions appear excessively or, conversely, are extremely suppressed. - Negative self-concept Persistent experiences of shame, guilt, feelings of failure, and worthlessness. - Difficulties in interpersonal relationships Persistent struggles in maintaining relationships and feeling close to others. ➡️These three collectively are called "Disturbances of Self-Organization." 😺Disturbances of self-organization are part of the diagnostic criteria for Complex PTSD and contribute to various symptoms, including functional impairments. 💫Functional Impairment A state in which illness causes various obstacles in daily life, leading to difficulties. For example: - Self-care (eating, changing clothes, etc.) - Housework (shopping, cleaning, laundry, etc.) - Interaction with others - Schooling and employment These activities become difficult. ➡️Even if one manages to do them, significant effort is required. 🐱ICD-11 does not have a clear definition or specific examples, but the WHO’s ICF provides a checklist for assessing functional impairments. 💫Chronic Dissociation and Somatization Tendency Dissociation A state where continuity, memory, and consciousness become fragmented or weakened. - Depersonalization: Feeling as if observing oneself from outside the body. - Derealization: Feeling that the world around oneself is "distorted," "distant," or "dreamlike." Somatization When psychological issues manifest as physical symptoms. ➡️Flashbacks and amnesia of basic PTSD are also well-known dissociative symptoms,

Dissociative Subtype of PTSD - In addition to the three core symptoms of PTSD (re-experiencing, avoidance, and hyperarousal), chronic dissociation (depersonalization, derealization) is present. 🐱 More details on these specific symptoms will be explained in the next post! ─── ⋆⋅☆⋅⋆ ──── Thank you so much for reading!

他の投稿はこちらから→@staa_psychology 他の投稿はこちらから→@staa_psychology <English Translation> 🐱We've looked at PTSD symptoms over the past four posts! What did everyone think? 🔴 "I only had a vague idea of PTSD before, but I was surprised to learn that so many different types of symptoms can appear!" 🔵 "I used to feel so down that I couldn't do things I was able to before, and I was filled with self-hatred. But knowing that this is also one of the symptoms made me feel a little relieved🥲" 🟡 "Hmm... Honestly, there are still some things I don't quite understand 🤔 So, in the end, how does someone get diagnosed with PTSD? Do all those symptoms have to be present?" 😺Let's check the PTSD diagnostic criteria! PTSD Diagnostic Criteria (DSM-5) ⭐️ Experience(directly/indirectly) a major traumatic event ⭐️ The following symptoms persist for more than one month: Intrusion/Re-experiencing symptoms: At least one Avoidance symptoms: At least one Negative alterations in cognition and mood: At least two Alterations in arousal and reactivity: At least two ⭐️ Significant distress or functional impairment ⭐️ Symptoms are not due to medication or another illness 🟡: Oh, I see! So, a certain number of items from each group must be met to make a diagnosis💡 🔴: You know, I have a question. For example, insomnia is categorized under the "Arousal and Reactivity" group, right? But nightmares fall under the "Intrusion and Re-experiencing" group. So, if someone’s insomnia is caused by nightmares, how should it be counted? 🔵: Yeah, that’s a good point. It’s a bit off-topic, but recently, I’ve been getting tired easily, and I don’t know if it’s because of lack of sleep, but I’ve had constant headaches... I thought it might be because of PTSD, but it’s not listed in the diagnostic criteria. Does that mean it’s another illness?😨 But on social media, a lot of people in the trauma community struggle with physical symptoms… 😺Actually, there are discussions like this about diagnostic criteria! 👀 #トラウマ #PTSD #解離性障害 #ADHD #心理学 #精神医学 #心的外傷後ストレス障害 #Trauma #dissociativedisorder #psychology #psychiatry
他の投稿はこちらから→@staa_psychology 他の投稿はこちらから→@staa_psychology <English Translation> 💫What are Alterations in Arousal and Reactivity? These symptoms involve heightened sensitivity to stimuli, leading to disruptions in daily life, including sleep patterns, interpersonal relationships, and physical and mental well-being. Specifically: - Sleep disorders - Irritability and difficulty concentrating - Recklessness - Hyperarousal and hypervigilance 💫Sleep Disorders → Difficulty maintaining a healthy sleep rhythm and quality sleep For example: - Difficulty staying asleep, experiencing frequent nighttime or early morning awakenings - Shallow sleep, frequent nightmares, and an inability to achieve restful sleep - Difficulty falling asleep, leading to insufficient sleep duration 💫Irritability and Difficulty Concentrating → Becoming more sensitive to stimuli, leading to aggression toward people or objects and difficulty focusing on tasks that were previously manageable For example: - Being easily distracted and feeling restless, making it hard to sustain attention - Constantly feeling tense and on edge, making it difficult to relax - Becoming irritated by things that would not usually be bothersome 💫Recklessness → Engaging in dangerous or self-destructive behaviours For example: - Impulsively spending money on gambling, gaming, or shopping - Engaging in risky sexual behaviors impulsively (which may also be a reenactment of trauma) - Binge eating, excessive alcohol consumption, or drug overuse 💫Hyperarousal and Hypervigilance → Becoming excessively alert to sounds, movements, or situations reminiscent of traumatic events, leading to constant tension For example: - Being overly conscious of others' gazes and overanalyzing situations - Establishing (compulsive) routines to avoid danger and strictly adhering to them - Experiencing physical symptoms such as sweating, increased heart rate, or shortness of breath ─── ⋆⋅☆⋅⋆ ──── Thank you so much for reading!

Specific Examples: - Negative beliefs and expectations - Negative emotions and thoughts - Loss of interest and positive emotions - Blame 💫Negative Beliefs and Expectations →Persistently viewing oneself, others, and the world in an excessively negative manner. For example: - Holding negative beliefs about oneself: "I am a bad person.", "I deserve to suffer." - Holding negative beliefs about others: "No one can be trusted.", "People will always betray me." - Holding negative beliefs about the world: "The world is a dangerous place.", "There is no safe place anywhere." 💫Negative Emotions and Thoughts →Experiencing persistent emotions such as guilt, shame, anger, or fear. For example: - Thinking "Because I was harmed, I am dirty and shameful." - Feeling sudden waves of anxiety and crying for no apparent reason in daily life. - Believing that one's presence is a burden to others. 💫Loss of Interest and Positive Emotions →A reduced ability to engage in activities that were once enjoyable or to experience happiness and satisfaction. For example: - Losing interest in hobbies or work. - Feeling distant from close friends, family, or a romantic partner. - Experiencing a sense of emptiness and an inability to enjoy anything. 💫Blame Excessively blaming oneself or others for events or their outcomes.

他の投稿はこちらから→@staa_psychology 他の投稿はこちらから→@staa_psychology <English Translation> 💫What Is Avoidance? Avoidance refers to symptoms in which a person actively avoids traumatic events or anything that reminds them of those events. Specific Examples: - Avoidance of thoughts, emotions, and memories - Avoidance of triggers 💫Avoidance of Thoughts, Emotions, and Memories → Avoiding thinking about or remembering the traumatic event itself. For example: - Avoiding talking about the traumatic event or the perpetrator. - Trying to make light of the event by joking about it (suppressing feelings of shame or fear). - Being unable to recall parts of the event (dissociative amnesia). 💫Avoidance of Triggers → Avoiding situations, places, people, conversations, objects, or activities that may bring back memories of the traumatic event. For example: - Being unable to visit the place where the trauma occurred or avoiding certain modes of transportation. - Avoiding interactions with people who share characteristics (race, age, gender, etc.) with the perpetrator. - Losing interest in hobbies or work that were previously enjoyable. ─── ⋆⋅☆⋅⋆ ──── Thank you so much for reading!

他の投稿はこちらから→@staa_psychology 他の投稿はこちらから→@staa_psychology <English Translation> 💫What Are Intrusions and Re-experiencing? Symptoms that make past events (trauma) feel as if they are happening again in the present. - Flashbacks and nightmares - Intrusive thoughts - Psychological and physical distress 💫Flashbacks & Nightmares → Feeling or acting as if the traumatic event is happening again. For example: - Repeatedly having distressing dreams (nightmares) about the traumatic event. - Hearing the perpetrator’s words as if they are being spoken right behind you. - Reenacting the traumatic event during play (common in children). 💫Intrusive Thoughts → Thoughts or images related to the trauma repeatedly arise against one's will. For example: - Thinking obsessively, “If only I had done this,” or “It was my fault.” - Feeling overwhelmed by persistent, intense anger toward the perpetrator. - Compulsively searching social media for information related to the traumatic event. 💫Psychological & Physical Distress → Experiencing rapid breathing, an increased heart rate, or emotional distress when exposed to triggers. For example: - Feeling intense heart palpitations and shortness of breath when encountering someone who resembles the perpetrator. - Suddenly experiencing physical pain or itching when talking about the trauma. - Feeling depressed when facing a situation similar to the one in which the trauma occurred. ─── ⋆⋅☆⋅⋆ ──── Thank you so much for reading!
