Social (pragmatic) communication disorder (SPCD), also known assemantic-pragmatic communication disorder, orpragmatic language impairment (PLI), is aneurodevelopmental disorder characterized by difficulties in the social use of verbal andnonverbal communication. Individuals with SPCD struggle to effectively indulge in social interactions, interpretsocial cues, and may struggle to use words appropriately in social contexts.
This disorder can have a profound impact on an individual's ability to establish and maintain relationships, navigate social situations, and participate in academic and professional settings.
While SPCD shares similarities with othercommunication disorders, such asautism spectrum disorder (ASD), it is recognized as a distinct diagnostic category with its own set ofdiagnostic criteria and features.
SPCD was granted its own category in theDSM-5 in 2013.[1] The creation of this new category allowed individuals to be considered affected by a form of communication disorderdistinct from autism spectrum disorder (ASD).[2] SPCD lacks behaviors associated withrestrictions andrepetition which are seen in ASD.[3]

Individuals withsocial communication disorder have particular trouble understanding the meaning of what others are saying. Children with the disorder often exhibit:[This paragraph needs citation(s)]
According to Bishop and Norbury (2002), children with semantic pragmatic disorder can have fluent, complex articulated expressive language but exhibit problems with the way their language is used. These children typically areverbose. However, they usually have problems understanding and producing connected discourse, instead giving conversational responses that are sociallyinappropriate,tangential, andstereotyped. They often develop eccentric interests but are not as strong or obsessional as people withautism.[4]
The current view is that the disorder has more to do with communication and information processing than language. For example, children with semantic-pragmatic disorder will often fail to grasp the central meaning orsaliency of events. This then leads to an excessive preference for routine and "sameness" (seen in autism spectrum disorder). Individuals often assume a literal communication. This would mean that obvious, concrete instructions are clearly understood and carried out, whereas simple butnon-literal expressions such asjokes,sarcasm, and general social chatting are difficult and can lead to misinterpretation. Lies are also a confusing concept to children with SCD as it involves knowing meaning beyond a literal interpretation.[This paragraph needs citation(s)]
Because SPCD has been categorized only since 2013, diagnosis is yet to be fully established. In theDSM-5, the child is diagnosed with SPCD if the child does not meet the criteria for other disorders such asASD andPDD-NOS.[1]
TheDSM-5 categorizes SPCD as acommunication disorder within the domain ofneurodevelopmental disorders, listed alongside other disorders of speech and language that typically manifest in early childhood. The DSM-5 diagnostic criteria for social communication disorder are as follows:
- A. Persistent difficulties in the social use of verbal and nonverbal communication as manifested by all of the following:
- Deficits in using communication for social purposes, such as greeting and sharing information, in a manner that is appropriate for the social context.
- Impairment of the ability to change communication to match the context or the needs of the listener, such as speaking differently in a classroom than on a playground, talking differently to a child than to an adult, and avoiding the use of overly formal language.
- Difficulties following rules for conversation and storytelling, such as taking turns in conversation, rephrasing when misunderstood, and knowing how to use verbal and nonverbal signals to regulate interaction.
- Difficulties understanding what is not explicitly stated (e.g., making inferences) and non-literal or ambiguous meanings of language (e.g.,idioms, humor,metaphors, multiple meanings that depend on the context for interpretation).
- B. The deficits result in functional limitations in effective communication, social participation, social relationships, academic achievement, or occupational performance, individually or in combination.
- C. The onset of symptoms is in the early developmental period (but deficits may not become fully manifest until social communication demands exceed limited capacities).
- D. The symptoms are not attributable to another medical or neurological condition or low abilities in the domains of word structure and grammar and are not better explained byautism spectrum disorder,intellectual disability (intellectual developmental disorder),global developmental delay, or another mental disorder.[citation needed]
Common assessments used to identify SPCD are:
Although several tests can be done to try to identify SPCD, some tests are better suited to diagnose SPCD than others. Also, there is not a specific assessment or test that can diagnose SPCD, unlike other disorders such as ASD,DLD, and PLI.[citation needed]

Treatments for SPCD are less established than for treatments for other disorders such as autism.[5] Similarities between SPCD and some aspects of autism lead some researchers to try some treatments for autism with people with SPCD.[6]
Speech therapy can help individuals who have communication disorders. Speech and language therapy treatment focuses on communication and social interaction.[7] Speech therapists can work with clients on communication in various settings.[7]
Hyperlexia is a similar but different disorder where the main characteristics are an above-average ability to read with a below-average ability to understand spoken or written language. Joanne Volden wrote an article in 2002 comparing the linguistic weaknesses of children with anonverbal learning disability to PLI.[8]
Communication problems are also part of the autism spectrum disorder (autism); however, individuals with autismalso show a restricted pattern of behavior, according to behavioral psychologists. The diagnosis of SPCD can only be given if autism has been ruled out.[9] It is assumed that those with autism have difficulty with the meaning of what is being said due to different ways of responding to social situations.
Before the release of the DSM-5 in 2013, SPCD was not differentiated from a diagnosis of autism. However, there were a large number of cases of children experiencing difficulties with pragmatics that did not meet the criteria for autism. The differential diagnosis of SPCD allows practitioners to account for social and communication difficulties which occur to a lesser degree than in children with autism.[10] Social communication disorder is distinguished from autism by the absence of any history (current or past) ofrestricted orrepetitive patterns of interest or behavior in SPCD.[11]
In 1983,Rapin and Allen suggested the term "semantic pragmatic disorder" to describe the communicative behavior of children who presented traits such as pathological talkativeness, deficient access tovocabulary and discourse comprehension, atypical choice of terms, and inappropriate conversational skills.[12] They referred to a group of children who presented with mildautistic features and specific semantic pragmatic language problems. In the late 1990s, the term "pragmatic language impairment" (PLI) was proposed.[13][14]
Rapin and Allen's definition has been expanded and refined by therapists who include communication disorders that involve difficulty in understanding the meaning of words, grammar, syntax, prosody, eye gaze, body language, gestures, or social context. While autistic children exhibit pragmatic language impairment, this type of communication disorder can also be found in individuals with other types of disorders includingauditory processing disorders,neuropathies,encephalopathies, and certain genetic disorders.[4]
Before the release of the DSM-5, there was debate over the relationship between semantic-pragmatic disorder and autistic disorder, as the clinical profile of semantic-pragmatic disorder is often seen in children withhigh-functioning autism.[15] Before the DSM-5 specified SPCD as a separate diagnosis, people with SPCD symptoms were often diagnosed withpervasive developmental disorder not otherwise specified (PDD-NOS).[16]
As mentioned in the introduction, SPCD has only been around since 2013. Before it emerged as its disorder SPCD could have fallen intoASD,PLI,DLD, etc. The reason is that several of these disorders include an issue with social communication.[17] In terms of developmental language disorder (DLD), individuals with this disorder have issues with language form and content and there seems to be no developmental cause.[17] In social environments, DLD seemed to have fewer difficulties than SPCD.[17]
In regards to ASD, ASD behaviors normally involve repetitive behaviors[1] which are normally not present in SPCD. It does not mean that SPCD does not show such behaviors.[1]
PLI tends to be the disorder that is more common to SPCD than the other disorders because both disorders are focused on the pragmatic difficulties individuals have in language with both disorders.[18] SPCD has an element of social communication that is lacking or undeveloped, unlike PLI.[3]
In terms ofSpecific language impairment, there tend to be a lot of similarities between SCPD and PLI but SLI deals with Semantic-Pragmatic issues.[3] This means that several issues fall into Semantic-Pragmatic issues such as uncommon word choice, speaking to oneself out loud and interesting, unimpaired phonology, and syntax.[3]
