Question: Does autism effect interpersonal skills?

Social skills

A social skill is any competence facilitating interaction and communication with others where social rules and relations are created, communicated, and changed in verbal and nonverbal ways. The process of learning these skills is called socialization. For socialization, interpersonal skills are essential to relate to one another. Interpersonal skills are the interpersonal acts a person uses to interact with others, which are related to dominance vs. submission, love vs. hate, affiliation vs. aggression, and control vs. autonomy categories (Leary, 1957). Positive interpersonal skills include persuasion, active listening, delegation, and stewardship, among others. A healthy Social interest (Gemeinschaftsgefühl) that involves more than being in a group is required for well-adjusted social skills. Social psychology is the academic discipline that does research related to social skills and studies how skills are learned by an individual through changes in attitude, thinking, and behavior.
Enumeration and categorization
Social skills are the tools that enable people to communicate, learn, ask for help, get needs met in appropriate ways, get along with others, make friends, develop healthy relationships, protect themselves, and in general, be able to interact with the society harmoniously.[1] Social skills build essential character traits like trustworthiness, respectfulness, responsibility, fairness, caring, and citizenship. These traits help build an internal moral compass, allowing individuals to make good choices in thinking and behavior, resulting in social competence.
The important social skills identified by the Employment and Training Administration are:
Coordination – Adjusting actions in relation to others' actions.
Mentoring – Teaching and helping others how to do something (e.g. a study partner).
Negotiation – Discussion aimed at reaching an agreement.
Persuasion – The action or fact of persuading someone or of being persuaded to do or believe something.
Service Orientation – Actively looking for ways to evolve compassionately and grow psycho-socially with people.
Social Perceptiveness – Being aware of others' reactions and able to respond in an understanding manner.
Social skills are goal oriented with both main goals and sub-goals.[2] For example, a workplace interaction initiated by a new employee with a senior employee will first contain a main goal. This will gather information, and then the sub-goal will be to establish a rapport in order to obtain the main goal.[3] Takeo Doi in his study of consciousness distinguished this as tutemae, meaning conventions and verbal expressions and honne, meaning true motive behind the conventions.[4]
Causes of deficits
Deficits in social skills were categorized by Gresham in 1998, as failure to recognize and reflect social skills, a failure to model appropriate models, and failure to perform acceptable behavior in particular situations in relation to developmental and transitional stages.[5] Social skill deficits are also a discouragement for children with behavioral challenges when it comes to adult adjustment.[6]
Alcohol
Social skills are significantly impaired in people suffering from alcoholism. This is due to the neurotoxic effects of alcohol on the brain, especially the prefrontal cortex area of the brain. The social skills that are impaired by alcohol abuse, include impairments in perceiving facial emotions, prosody perception problems, and theory of mind deficits. The ability to understand humor is also impaired in alcohol abusers.[7] Impairments in social skills can also occur in individuals who suffer from fetal alcohol spectrum disorders. These deficits persist throughout the affected people's lives, and may worsen over time due to the effects of aging on the brain.[8]
ADHD and hyperkinetic disorder
People with ADHD and hyperkinetic disorder[9] often have difficulties with social skills, such as social interaction. Approximately half of ADHD children and adolescents will experience peer rejection, compared to 10–15 percent of non-ADHD youth. Adolescents with ADHD are less likely to develop close friendships and romantic relationships; they are usually regarded by their peers as immature or as social outcasts, with an exception for peers that have ADHD or related disorders themselves, or a high level of tolerance for such symptoms. As they begin to mature, however, it becomes easier to make such relationships. Training in social skills, behavioral modification, and medication have some beneficial effects. It is important for ADHD youth to form friendships with people who are not involved in deviant/delinquent activities and/or significant mental illness/developmental disabilities  in order to reducing emergence of later psychopathology. Poor peer relationships can contribute to major depression, criminality, school failure, and substance use disorders.[10][11]
Autism
People with autistic spectrum disorders are often deficient in social skills. This is most likely the result of the lack of theory of mind, which enables the person to understand other people's emotions. The concept of social skills has been questioned in terms of autistic spectrum.[12] In response for the needs of children with autism, Romanczyk has suggested for adapting comprehensive model of social acquisitions with behavioral modification rather than specific responses tailored for social contexts.[13]
Anxiety and depression
Individuals with few opportunities to socialize with others often struggle with social skills. This can often create a downward spiral effect for people with mental illnesses like anxiety or depression. Due to anxiety experienced from concerns with interpersonal evaluation and fear of negative reaction by others, surfeit expectations of failure or social rejection in socialization leads to avoiding or shutting down from social interactions.[14] Individuals who experience significant levels of social anxiety often struggle when communicating with others, and may have impaired abilities to demonstrate social cues and behaviors appropriately.[15] Specially teens that use social media all the time socialize less. The use of social media can also cause anxiety and depression.Internet is causing many problems, according to a study from the National library of Medicine, National institute of health, with a sample size of 3560 students. Problematic internet use may be present in about 4% of high school students in the United States, it may be associated with depression. About one third of respondents (28.51%) reported spending fifteen or more hours per week on the internet.[16]
Depression can also cause people to avoid opportunities to socialize, which impairs their social skills, and makes socialization unattractive.[17]
Anti-social behaviors

The authors of the book Snakes in Suits: When Psychopaths Go to Work explore psychopathy in workplace. The FBI consultants describe a five phase model of how a typical psychopath climbs to and maintains power. Many traits exhibited by these individuals include: superficial charm, insincerity, egocentricity, manipulativeness, grandiosity, lack of empathy, low on agreeableness, exploitativeness, independence, rigidity, stubbornness and dictatorial tendencies. Babiak and Hare say for corporate psychopaths, success is defined as the best revenge and their problem behaviors are repeated "ad infinitum" due to little insight and their proto-emotions such as "anger, frustration, and rage" is refracted as irresistible charm. The authors note that lack of emotional literacy and moral conscience is often confused with toughness, the ability to make hard decisions, and effective crisis management. Babiak and Hare also emphasizes a reality they identified with psychopaths from studies that psychopaths are not able to be influenced by any sort of therapy.[18][19]
At the University at Buffalo in New York, Emily Grijalva has investigated narcissism in business; she found there are two forms of narcissism: "vulnerable" and "grandiose".[20] It is her finding that "moderate" level of grandiose narcissism is linked to becoming an effective manager. Grandiose narcissists are characterized as confident; they possess unshakable belief that they are superior, even when it's unwarranted. They can be charming, pompous show-offs, and can also be selfish, exploitative and entitled.[21] Jens Lange and Jan Crusius at the University of Cologne, Germany associates "malicious-benign" envy within narcissistic social climbers in workplace. It is their finding that grandiose narcissists are less prone to low self-esteem and neuroticism and are less susceptible to the anxiety and depression that can affect vulnerable narcissists when coupled with envy. They characterize vulnerable narcissists as those who "believe they are special, and want to be seen that way–but are just not that competent, or charming." As a result, their self-esteem fluctuates a lot. They tend to be self-conscious and passive, but also prone to outbursts of potentially violent aggression if their inflated self-image is threatened."[22] Richard Boyatzis says this is an unproductive form of expression of emotions that the person can’t share constructively, which reflects lack of appropriate skills.[23] Eddie Brummelman, a social and behavioral scientist at the University of Amsterdam in the Netherlands and Brad Bushman at Ohio State University in Columbus says studies show that in western culture narcissism is on the rise from shifting focus on the self rather than on relationships and concludes all narcissism to be socially undesirable ("unhealthy feelings of superiority"). David Kealy at the University of British Columbia in Canada states that narcissism might aid temporarily but in the long run it is better to be true to oneself, have personal integrity, and be kind to others.[24]
Management
Behavior therapy

To behaviorists, social skills are learned behaviors that allow people to achieve social reinforcement. According to Schneider & Byrne (1985), who conducted a meta-analysis of social skills training procedures (51 studies), operant conditioning procedures for training social skills had the largest effect size, followed by modeling, coaching, and social cognitive techniques.[25] Behavior analysts prefer to use the term behavioral skills to social skills.[26] Behavioral skills training to build social and other skills is used with a variety of populations including in packages to treat addictions as in the community reinforcement approach and family training (CRAFT).[27]
Training of behavioral skills is also used for people who suffer from borderline personality disorder,[28]
depression,[29] and developmental disabilities.[26][30]  Typically behaviorists try to develop what are considered cusp skills,[31] which are critical skills to open access to a variety of environments.  The rationale for this type of approach to treatment is that people meet a variety of social problems and can reduce the stress and punishment from the encounter in a safe environment. It also addresses how they can increase reinforcement by having the correct skills.
