NSYNC was an American boy band formed in Orlando, Florida, in 1995 and launched in Germany by BMG Ariola Munich. NSYNC consisted of Justin Timberlake, JC Chasez, Chris Kirkpatrick, Joey Fatone, Lance Bass. After publicized legal battles with their former manager Lou Pearlman and former record label Bertelsmann Music Group, the group's second album, No Strings Attached, sold over one million copies in one day and 2.42 million copies in one week, a record for over fifteen years. Among the group's singles, "I Want You Back", "Bye Bye Bye", "This I Promise You", "Girlfriend", "Pop" and "It's Gonna Be Me" reached the top 10 in several international charts, with the last being a US Billboard Hot 100 number one. In addition to a host of Grammy Award nominations, NSYNC has performed at the World Series, the Super Bowl and the Olympic Games, sang or recorded with Elton John, Stevie Wonder, Michael Jackson, Janet Jackson, Britney Spears, Phil Collins, Celine Dion, Nelly, Left Eye, Mary J. Blige, country music supergroup Alabama, Gloria Estefan.

NSYNC last recorded new material in 2002. The band completed five nationwide concert tours and has sold between 50 and 70 million records, becoming the fifth-best-selling boy band in history. Rolling Stone recognized their instant success as one of the Top 25 Teen Idol Breakout Moments of all time. Justin Timberlake went on to become a ten-time Grammy Award winner throughout his solo career. Chris Kirkpatrick, who had missed the cut for the Backstreet Boys, met with Lou Pearlman in 1995 to talk about forming a second group. Pearlman said; this prompted Kirkpatrick to call Joey Fatone, a friend he had met while working at Universal Studios. Fatone and Kirkpatrick approached Lou Pearlman for more suggestions. Pearlman looked through some tapes they had, one of Justin Timberlake from The Mickey Mouse Club caught his eye. Timberlake soon joined the group and recommended his friend JC Chasez, a cast member on Walt Disney Channel's Mickey Mouse Club. Soon, they decided to out their sound by recruiting Jason Galasso as their bass singer.

NSYNC received its name after Justin Timberlake's mother commented on how "in sync" the group's singing voices were. The group's name is a play on the last letter of each of the initial members' names: JustiN, ChriS, JoeY, JasoN, JC. After several weeks of rehearsals, the group set up a showcase and began planning to sign with Pearlman's Trans Continental Label. However, at the last minute, Galasso dropped out, he was not fond of the group's musical direction, claiming that being a teen idol was never a goal of his. In need of a bass, the group auditioned several people without success. Timberlake soon called his vocal coach, who suggested a 16-year-old from Mississippi named Lance Bass. Bass flew to Orlando to audition and was accepted into the group, he was nicknamed "Lansten" so they could keep the name'NSYNC. From there, Pearlman set the five boys up in a house in Orlando, where they rehearsed learning dance routines and vocal parts, working on promotion for their first public performance at Pleasure Island on October 22, 1995.

Pearlman hired manager of the Backstreet Boys, to manage the group. NSYNC sent him a two-song demo-tape including "I'll Be Back for More" and "We Can Work It Out", which impressed him; the group performed for a group of BMG executives. Although the record company had some concerns with the band's name and Bass's dancing abilities, they agreed to sign the group to BMG Ariola Munich with Wright as their manager. After being signed to BMG Ariola Munich, the group was sent to Sweden to begin working on their debut album with the help of producers such as Denniz Pop, Max Martin and Andreas Carlsson; the album's official lead single, "I Want You Back", was released in Germany on October 7, 1996, entered the top 10 in Germany on November 18, 1996. With a record deal secured, the boys began touring first in German-speaking countries and in other European territories, their self-titled debut album was released by BMG Ariola Munich on May 26, 1997, in Germany, peaked at number one in the second week after its release.

The group soon became an overnight success throughout much of Europe. The album charted in both Switzerland and Austria selling 820,000 units in GSA region and Eastern Europe; the group released its second and third singles, "Tearin' Up My Heart" and "Here We Go", both of which managed to reach the top-10 in numerous countries in Europe. NSYNC captured the attention of an A&R rep for RCA Records. After seeing the group perform in Budapest, he signed them to RCA in 1998; the American label had the group record some new tracks to adjust their album for the US market. The group released its debut American single, "I Want You Back" on January 20, 1998, it reached No. 13 on the Billboard Hot 100. An album called'N Sync followed on March 24, 1998. Album sales were sluggish, debuting at No. 82 on the Billboard 200, but were helped when the Disney Channel aired a concert special on July 18, 1998. The concert was first offered to the Backstreet Boys, but they had to back out due to member Brian Littrell needing heart surgery doing their own special in 1999.

Three weeks before the concert, the album sat at No. 85 on the albums chart. The group's profile continued the rise with subsequent single release "Tearin' Up My Heart", which became a hit on pop radio and one of the "100 Greatest Songs of the 90's" ac

Complex post-traumatic stress disorder is a psychological disorder that can develop in response to prolonged, repeated experience of interpersonal trauma in a context in which the individual has little or no chance of escape. C-PTSD relates to the trauma model of mental disorders and is associated with chronic sexual and narcissistic abuse and physical abuse and neglect, chronic intimate partner violence, victims of prolonged workplace or school bullying, victims of kidnapping and hostage situations, indentured servants, victims of slavery and human trafficking, sweatshop workers, prisoners of war, concentration camp survivors, residential school survivors, defectors of cults or cult-like organizations. Situations involving captivity/entrapment can lead to C-PTSD-like symptoms, which can include prolonged feelings of terror, worthlessness and deformation of one's identity and sense of self. C-PTSD has been referred to as DESNOS or Disorders of Extreme Stress Not Otherwise Specified; some researchers believe that C-PTSD is distinct from, but similar to, PTSD, somatization disorder, dissociative identity disorder, borderline personality disorder.

Its main distinctions are a distortion of the person's core identity and significant emotional dysregulation. It was first described in 1992 by an American psychiatrist and scholar, Judith Herman in her book Trauma & Recovery and in an accompanying article; the disorder is included in the World Health Organization's eleventh revision of the International Statistical Classification of Diseases and Related Health Problems. The C-PTSD criteria has not yet gone through the private approval board of the American Psychiatric Association for inclusion in the Diagnostic and Statistical Manual of Mental Disorders. Complex PTSD is recognized by the United States Department of Veterans Affairs, Healthdirect Australia, the National Health Service; the diagnosis of PTSD was developed for adults who had suffered from a single-event trauma, such as rape, or a traumatic experience during a war. However, the situation for many children is quite different. Children can suffer chronic trauma such as maltreatment, family violence, a disruption in attachment to their primary caregiver.

In many cases, it is the child's caregiver. The diagnosis of PTSD does not take into account how the developmental stages of children may affect their symptoms and how trauma can affect a child’s development; the term developmental trauma disorder has been proposed as the childhood equivalent of C-PTSD. This developmental form of trauma places children at risk for developing psychiatric and medical disorders. Dr. Bessel van der Kolk explains DTD as numerous encounters with interpersonal trauma such as physical assault, sexual assault, violence or death, it can be brought on by subjective events such as betrayal, defeat or shame. Repeated traumatization during childhood leads to symptoms that differ from those described for PTSD. Cook and others describe symptoms and behavioural characteristics in seven domains: Attachment – "problems with relationship boundaries, lack of trust, social isolation, difficulty perceiving and responding to others' emotional states" Biology – "sensory-motor developmental dysfunction, sensory-integration difficulties and increased medical problems" Affect or emotional regulation – "poor affect regulation, difficulty identifying and expressing emotions and internal states, difficulties communicating needs and wishes" Dissociation – "amnesia, depersonalization, discrete states of consciousness with discrete memories and functioning, impaired memory for state-based events" Behavioural control – "problems with impulse control, pathological self-soothing, sleep problems" Cognition – "difficulty regulating attention.

Self-concept – "fragmented and disconnected autobiographical narrative, disturbed body image, low self-esteem, excessive shame, negative internal working models of self". Adults with C-PTSD have sometimes experienced prolonged interpersonal traumatization beginning in childhood, rather than, or as well as, in adulthood; these early injuries interrupt the development of others. Because physical and emotional pain or neglect was inflicted by attachment figures such as caregivers or older siblings, these individuals may develop a sense that they are fundamentally flawed and that others cannot be relied upon; this can become a pervasive way of relating to others in adult life, described as insecure attachment. This symptom is neither included in the diagnosis of dissociative disorder nor in that of PTSD in the current DSM-5. Individuals with Complex PTSD demonstrate lasting personality disturbances with a significant risk of revictimization. Six clusters of symptoms have been suggested for diagnosis of C-PTSD: alterations in regulation of affect and impulses.

Experiences in these areas may include: Changes in emotional regulation, including experiences such as persistent dysphoria, chronic suicidal preoccupation, self-injury, explosive or extremely
